1309 Optics by al-Farisi
2018 SOLD for £ 550K by Sotheby's
In antique times, scientific knowledge was transmitted through compilations, which the authors used to insert their own theories. Forgotten, quite wrongly, in Europe, this effective method was perpetuated elsewhere for fifteen centuries, mostly by Arab scholars.
Al-Shirazi was one of these polygraphs. Like Aristotle, he was interested in everything : mathematics, astronomy, geography, philosophy, medicine, theology, law, linguistics, rhetoric. He was also a chess player, a musician and even a humorist.
Al-Farisi, who was one of his pupils, was asked around 700 AH in Tabriz a question about the refraction of light. The master, who was not a specialist in optics, gave him access to a copy dated 419 AH of the Book of Optics by Alhacen, who demonstrated that vision is a brain phenomenon resulting from the reflection of light on the object. The eye is no more than the optical organ which transmits this information.
In compliance with the best tradition, al-Farisi's personal contribution is very important. He studies in great detail the internal geometry of the eye to understand the aberrations of vision created by refraction. He models the drop of water to study the propagation of the sun's ray in its complex sequence of refractions and reflections. He is the very first to interpret the rainbow mathematically and improves the theory of colors.
Al-Farisi's working manuscript, partially autograph, rigorously reproduces the list of chapters from The Optics of Alhacen. It was completed in 708 AH corresponding to 1309 CE, two years before the death of al-Shirazi.
A large part of this document was sold for £ 550K by Sotheby's on April 25, 2018 from a lower estimate of £ 250K, lot 32. This set of 321 sheets 22 x 12 cm is illustrated with many figures in red ink. One of these is perhaps the oldest scientifically correct diagram of the internal structure of the eye.
Another section is held at the New York Public Library. It includes the colophons which show that this treatise had been in the hands of two very eminent Ottoman scholars.
Copies were made to transmit this knowledge. One of them, dated 899 AH, was sold for £ 110K by Sotheby's on October 25, 2017, lot 23.

masterpiece
1490 Vitruvian Man by Leonardo
Gallerie dell'Accademia, Venice
The Vitruvian Man (Italian: L'uomo vitruviano), created by Leonardo da Vinci around c. 1490, is one of the most iconic drawings in art and science history. This pen-and-ink study on paper (with some watercolor touches) measures approximately 34.4 × 24.5 cm (13.5 × 9.6 inches) and illustrates Leonardo's deep investigation into ideal human proportions, geometry, and the harmony between man and the cosmos.
Creation and Context
Leonardo produced the drawing during his time in Milan or shortly before/after, as part of his extensive anatomical and mathematical studies. It draws directly from the writings of the Roman architect Vitruvius (1st century BC), whose treatise De Architectura (On Architecture) describes how the human body can serve as the model for perfect architectural proportions. Vitruvius claimed the outstretched arms and legs of a man fit exactly within a circle and a square.Leonardo went further: he meticulously measured and corrected these ancient ratios based on his own observations of real human bodies (from live models and early dissections), refining them into what he saw as universal harmony.
Visual Composition and Key Details
The drawing depicts a nude male figure in two superimposed positions:
Leonardo added extensive notes in mirror writing (readable only in a mirror), explaining the proportions, citing Vitruvius, and discussing how the body relates to both geometry and architecture. The text blends observation, mathematics, and philosophy.
Symbolism and Deeper Meaning
The Vitruvian Man transcends a mere anatomical study:
The drawing is held in the permanent collection of the Gallerie dell'Accademia in Venice, Italy, where it has been since the early 19th century (acquired after passing through various private collections, including those of Venetian nobility). Due to its extreme fragility (ink on fragile paper), it is rarely displayed publicly and is kept in controlled conditions to prevent light damage. It was notably exhibited in 2019 for the 500th anniversary of Leonardo's death.The work has become a cultural icon, appearing in everything from textbooks and logos to popular media, symbolizing genius, proportion, and the fusion of art and science.Leonardo's Vitruvian Man remains a profound testament to his quest for understanding the "measure of man" in both literal and philosophical terms.

Visual Composition and Key Details
The drawing depicts a nude male figure in two superimposed positions:
- Arms and legs spread wide (forming a sort of "X" shape).
- Arms raised horizontally and legs together (forming a more upright "cruciform" pose).
- A circle (centered at the navel, symbolizing the cosmic or divine order).
- A square (aligned with the figure's extremities, representing earthly or material order).
- The height of the man equals the span of his outstretched arms (arm span = height).
- The distance from the sole of the foot to below the knee = 1/4 of height.
- From below the knee to the navel = 1/4 of height.
- From navel to top of head = 1/4 of height.
- The navel is the center of the circle.
- The breadth of the shoulders ≈ 1/4 of height.
- The face (from chin to hairline) is 1/10 of the total height.
- The hand (from wrist to fingertip) is 1/10 of height.
Leonardo added extensive notes in mirror writing (readable only in a mirror), explaining the proportions, citing Vitruvius, and discussing how the body relates to both geometry and architecture. The text blends observation, mathematics, and philosophy.
Symbolism and Deeper Meaning
The Vitruvian Man transcends a mere anatomical study:
- It represents the Renaissance ideal of humanism — man as the measure of all things, bridging microcosm (the body) and macrocosm (the universe).
- The circle and square symbolize the union of heavenly/divine (circle, eternal and infinite) and earthly/material (square, finite and stable) realms.
- It embodies Leonardo's belief in the interconnectedness of art, science, mathematics, and nature — using empirical study to reveal universal truths.
- Some interpretations see it as a symbol of balance, harmony, and the potential perfection of humanity.

De Humani Corporis Fabrica by VESALIUS
Intro
Andreas Vesalius (1514–1564), a Flemish physician and anatomist born in Brussels, is widely regarded as the founder of modern human anatomy. His groundbreaking work revolutionized the study of the human body by shifting from reliance on ancient authorities—primarily Galen (whose texts, based on animal dissections, contained numerous errors when applied to humans)—to direct, empirical observation through human cadaver dissections.
Vesalius performed public and private dissections himself (contrary to medieval custom where a barber-surgeon handled the body while a professor lectured from texts), often sourcing cadavers from executed criminals or grave-robbing (as he candidly described). This hands-on approach allowed unprecedented accuracy, correcting Galen's mistakes (e.g., in the liver, heart valves, and skeletal structure) and establishing anatomy as a descriptive science grounded in evidence rather than tradition.
Magnum Opus: De Humani Corporis Fabrica Libri Septem (1543)
Published in Basel when Vesalius was just 28–29, De Humani Corporis Fabrica ("On the Fabric of the Human Body in Seven Books") is a monumental, ~700-page encyclopedia of human anatomy. Dedicated to Emperor Charles V, it was printed by Johannes Oporinus and marked a turning point in medical publishing.
Key Anatomical Illustrations and Their Impact
Legacy
The Fabrica (with a 1555 revised edition) challenged scholastic medicine, sparked controversy (some called it heretical), but ultimately elevated surgery/anatomy and inspired the scientific revolution's emphasis on observation/experimentation. Vesalius became court physician to Charles V and Philip II but died young (at 50) after a shipwreck.Often called "the greatest medical book ever written" (per Sir William Osler), it bridged Renaissance humanism, classical revival, and empirical science—much like Leonardo's sketches but more systematically published and influential in medicine. Vesalius's insistence on direct human evidence laid the foundation for modern anatomy, separating it from ancient dogma.

Dedicated to Emperor Charles V, it was printed by Johannes Oporinus and marked a turning point in medical publishing.
- Structure: Divided into seven books covering bones, muscles, vessels, nerves, organs, reproductive system, and more.
- Innovations: Vesalius insisted physicians perform dissections personally, criticizing the "detestable procedure" of delegating to assistants. He urged initiative in obtaining bodies and used comparative anatomy (human vs. animal) to highlight differences.
- Aesthetic and scientific fusion: The book blended rigorous science with Renaissance artistry, featuring over 200 woodcut illustrations (likely from Titian's workshop, possibly including Jan Steven van Calcar). These were the first comprehensive, precise, and integrated anatomical plates—full-page, layered views, cross-sections, and dynamic poses that made anatomy visually accessible and beautiful.
Key Anatomical Illustrations and Their Impact
- Skeletons: Thoughtful, posed figures (e.g., leaning on a pedestal or in contemplative stances) with accurate proportions and labels, correcting Galen's primate-based errors.
- Muscular figures: Layered dissections showing superficial to deep muscles, often in heroic, dynamic poses with flayed skin draped or removed, emphasizing structure and function.

1543 1st edition
1998 SOLD for $ 1.65M by Christie's
Andries van Wesel, who latinized his name as Andreas Vesalius, was one of the founders of modern science and one of the scientists whose work had the greatest impact on our civilization. He is the explorer of the human body.
Born to a family of doctors, he observed the decomposed corpses on the gibbet of Brussels, in front of his home. He early appreciated that only direct observation could lead to a suitable understanding.
Not only he refuted all the errors of Galen which had prevented the progress of medicine and surgery, but also he explained the reason why : in order not to defy the taboos of the Roman Empire, Galen had dissected monkeys. An example among so many progresses is the analysis of breathing by which Vesalius paves the way for life saving ventilation.
His drawings are plagiarized and challenged. Vesalius therefore decides that he must collect his observations and figures in a masterly work. After four years of preparation, De Humani Corporis Fabrica 'libri septem' (meaning in seven books) is published in Basel in folio format 43 x 28 cm in 1543.
The anatomical drawings were prepared in Venice by an anonymous artist, probably from Titian's studio. Some vitality was added by staging écorchés and skeletons in landscapes of the Padua countryside.
A copy owned by the Emperor Charles V, considered to be his dedication copy, was sold by Christie's on March 18, 1998 for $ 1.65M from a lower estimate of $ 400K, lot 213. All illustrations including initials had been colored with highlights in liquid gold and silver.

1628 Exercitatio Anatomica by Harvey
2025 SOLD for £ 1.02M by Christie's
William Harvey's discovery of the circulation of the blood represents one of the most transformative breakthroughs in the history of medicine and physiology. Born in 1578 in Folkestone, England, Harvey (1578–1657) was an English physician, anatomist, and royal physician to both James I and Charles I. Trained at the University of Padua (under Fabricius, who discovered venous valves), he combined meticulous dissection, vivisection (on living animals), quantitative measurement, and experimental logic to overturn 1,400+ years of Galenic dogma.
In the Galenic system (dominant since the 2nd century AD), blood was thought to be produced in the liver, flow outward through veins to nourish tissues (where it was consumed), and move slowly/eb and flow rather than circulate. Arteries contained a different "vital spirit," and the heart merely heated blood or allowed minor seepage between ventricles via invisible pores.
Harvey demolished this in his seminal 1628 publication: Exercitatio Anatomica de Motu Cordis et Sanguinis in Animalibus (De Motu Cordis or "On the Motion of the Heart and Blood in Animals"), a concise 72-page Latin treatise published in Frankfurt.
Core Discovery and Key Arguments
Harvey demonstrated that blood circulates continuously in a closed loop, propelled mechanically by the heart acting as a pump:
Harvey's proof relied on observation, calculation, and simple but ingenious demonstrations:
Illustrations from De Motu Cordis
The book included woodcut figures (e.g., arm ligature experiments showing valves and blood flow direction) that visually proved unidirectional venous return.

Core Discovery and Key Arguments
Harvey demonstrated that blood circulates continuously in a closed loop, propelled mechanically by the heart acting as a pump:
- Blood is ejected from the heart into arteries during systole (contraction).
- It returns via veins to the heart during diastole (relaxation).
- This forms a double circulation: pulmonary (heart → lungs → heart) and systemic (heart → body → heart).
- The heart's sole function is propulsion; it does not "attract" blood or generate it anew.
Harvey's proof relied on observation, calculation, and simple but ingenious demonstrations:
- Quantitative measurement: He estimated ventricular volume (about 2 ounces) and heartbeat rate (72/min). In half an hour, the heart pumps far more blood (several pounds) than the body could produce or consume—impossible unless blood recirculates.
- Ligature experiments (using tourniquets on arms):
- Tight ligature stops arterial inflow → arm swells below but veins empty above.
- Loose ligature (blocking veins but not arteries) → veins swell below the band, showing blood flows toward the heart in veins.
- Pressing blood away from the heart past a valve → segment remains empty, proving unidirectional flow due to valves (building on Fabricius's discovery).
- Vivisections (on cold-blooded animals like snakes/frogs for slower observation): Revealed heart contractions propel blood forward; valves prevent backflow.
- Arterial/venous observations: Arteries pulsate with heartbeats; opening an artery shows forceful ejection; veins refill from periphery.
Illustrations from De Motu Cordis
The book included woodcut figures (e.g., arm ligature experiments showing valves and blood flow direction) that visually proved unidirectional venous return.
Significance and Legacy
- Revolutionary impact: Shifted physiology from qualitative/ancient authority to quantitative experiment and mechanism—paving the way for modern science (influencing figures like Descartes and Boyle).
- Initial reception: Controversial; some Galenists resisted, but acceptance grew in Harvey's lifetime (by 1650s widely adopted).
- Completion of the picture: Harvey inferred capillary connections (invisible without microscopes); Malpighi later confirmed them in 1661.
- Broader context: Parallels Vesalius (anatomy via direct observation) and anticipates the scientific method's emphasis on evidence over tradition.

Asking Grok to define progress in anatomy compared with Vesalius and find previous auction history for this Harvey title.
Progress in Anatomy: Harvey Compared to Vesalius
Andreas Vesalius (1514–1564) and William Harvey (1578–1657) represent pivotal figures in the evolution of anatomical science during the Renaissance and early Scientific Revolution, with Vesalius laying the foundational groundwork for empirical observation and Harvey extending it into functional understanding. Vesalius, often called the "father of modern anatomy," revolutionized the field by challenging the unchallenged authority of the ancient physician Galen (c. 129–c. 216 CE), whose anatomical descriptions were based primarily on animal dissections and had dominated medical education for over a millennium. Harvey, building directly on Vesalius's legacy, shifted anatomy from static description to dynamic physiology, particularly through his seminal work Exercitatio Anatomica de Motu Cordis et Sanguinis in Animalibus (1628), which demonstrated the circulation of blood.
To illustrate the comparative progress, consider the following key dimensions, comparing Vesalius's Contribution (c. 1543, De Humani Corporis Fabrica) and Harvey's Advancement (1628, De Motu Cordis)
Methodology
Vesalius : Emphasized direct human cadaver dissection over Galen's animal-based texts; corrected ~200 Galenic errors (e.g., Galen's claim that the humerus was the longest bone after the femur; Vesalius showed the tibia/fibula displaced it to fourth). Encouraged public dissections and artist-illustrated accuracy.
Harvey : Integrated Vesalian dissection with quantitative experiments (e.g., measuring heart output in animals) and vivisections; used valves discovered by his teacher Girolamo Fabrici (Vesalius's student) to infer systemic flow.
Progress : From qualitative observation to experimental quantification; Vesalius enabled "seeing," Harvey added "testing" for causation.
Scope of Anatomy
Vesalius : Structural/descriptive: Detailed human musculoskeletal, vascular, and organ systems in 7 volumes with groundbreaking woodcut illustrations (e.g., flayed figures in pastoral settings). Proved human-animal differences (e.g., no rete mirabile in human brain).
Harvey : Functional/physiological: Focused on cardiovascular system, proving blood circulates unidirectionally via the heart as a muscular pump, not Galen's ebb-and-flow model. Influenced by Realdo Colombo's pulmonary circuit (1559).
Progress : From morphology (form) to teleology (purpose); Vesalius mapped the body, Harvey explained its mechanics, unifying anatomy with natural philosophy.
Impact on Medicine
Vesalius : Shifted teaching from lecturing on texts to hands-on anatomy; inspired Padua School (where Harvey studied 1599–1602). Reduced reliance on humoral theory indirectly by accurate structures.
Harvey : "Cornerstone of modern physiology" (Garrison-Morton); enabled advances like Richard Lower's lung oxygenation (1669). Challenged bloodletting; faced initial resistance but gained rapid acceptance.
Progress : Vesalius dismantled dogma; Harvey applied it to hypothesize and verify, accelerating the Scientific Revolution (e.g., Descartes's mechanistic physiology).
Challenges Overcome
Vesalius : Legal/religious barriers to dissection; humanist revival of texts but prioritized experientia (experience).
Harvey : Galenic opposition (e.g., from Jean Riolan); lost patients due to "crack-pot" ideas undermining humors.
Progress : Cumulative: Vesalius's empirical foundation made Harvey's causal inferences possible; both emphasized "res publica literaria" (republic of letters) for collaborative progress.
In essence, Vesalius progressed anatomy by establishing it as an observational science independent of ancient authority, providing the precise human blueprint that Harvey used to deduce function. This progression reflects the Renaissance emphasis on historia (description) evolving into 17th-century scientia (causal knowledge), with Harvey explicitly crediting Padua's Vesalian tradition. Without Vesalius, Harvey's circulatory model—arrived at via dissections, measurements, and logical deduction—would lack the anatomical fidelity to convince contemporaries.
Auction History for Exercitatio Anatomica

The mechanism of the disease is not known when Whipple presumes that the liver has a role in it. He shows on dogs that the absorption of liver reverses the effects of an induced anemia. In 1926, Minot and Murphy use his results to prepare liver juice for patients showing syndromes of pernicious anemia. The disease is defeated.
The pharmaceutical story does not end at that point, fortunately. As early as 1928, another researcher who was not honored in the Nobel prize improved the diet by injecting liver extracts to the patient, avoiding him a daily swallow of a big quantity of liver food. In 1948, the cause of the pernicious anemia is identified as a deficiency of absorption by the intestine of a previously unidentified vitamin.
On September 21, 2015, Bonhams sold for $ 550K from a lower estimate of $ 200K the Nobel medal and diploma awarded to George Minot along with various related documents, lot 46. Please watch the video shared by Bonhams.
One of these documents is particularly noteworthy. Minot suffered from a severe diabetes. He had been saved from death by the discovery of insulin in 1921. Frederick Banting wrote from Toronto to congratulate him on his Nobel and to comfort him by stating that good quality insulin is also available in Sweden.
1934 Nobel prize to Minot. Define his influence on the advancement of Medicine.
George Richards Minot, an American physician, was awarded the Nobel Prize in Physiology or Medicine in 1934, shared with George Hoyt Whipple and William Parry Murphy, for their pioneering work on liver therapy for anemia, particularly pernicious anemia, which was previously a uniformly fatal condition.
Minot's primary contribution stemmed from his research beginning in the 1910s, where he became interested in blood disorders during his time at Massachusetts General Hospital. Building on Whipple's earlier experiments showing that a liver-rich diet stimulated blood cell formation in dogs with induced anemia, Minot and Murphy adapted this approach for humans in 1926. They demonstrated that patients with pernicious anemia experienced dramatic improvements when consuming large amounts of raw liver daily, reversing symptoms by replenishing red blood cells. This treatment illuminated the underlying cause: a deficiency in an intrinsic factor later identified as vitamin B12, which is abundant in liver.
His influence on medicine was profound and multifaceted:

His influence on medicine was profound and multifaceted:
- Transforming Pernicious Anemia Treatment: Prior to Minot's work, pernicious anemia led to inevitable death, often within months of diagnosis. The liver diet and subsequent development of oral liver extracts (in collaboration with chemist Edwin Cohn) provided the first effective therapy, saving countless lives until purified vitamin B12 became available in 1948. This shifted the disease from fatal to manageable, marking a milestone in hematology.
- Advancing Nutritional Medicine: Minot's findings highlighted the role of dietary factors in treating deficiency diseases, influencing broader research into vitamins and nutrition. It spurred investigations into other anemias and metabolic disorders, emphasizing how specific nutrients could correct physiological imbalances.
- Methodological and Institutional Impact: As director of the Thorndike Memorial Laboratory at Boston City Hospital from 1928, Minot fostered interdisciplinary research on blood diseases, training future physicians and contributing to studies on diabetes (from which he personally suffered), coagulation disorders, and leukemia. His emphasis on clinical experimentation and dietary interventions helped establish modern approaches to evidence-based medicine in endocrinology and hematology.
1953 Letter to his son by Crick
2013 SOLD for $ 6.1M by Christie's
Through a mathematical approach to X-Ray views that had been difficult to analyze, Crick and Watson built the model of the double helix of DNA. Copernicus had used a somehow similar method to raise the heliocentric hypothesis when seeking to simplify an apparently too complex data.
Very excited (as he told it), Francis Crick could not keep the secret. The listener is well chosen: he explains with great foresight the result and its consequences in a seven-page handwritten letter dated 19 March 1953 to his son Michael then twelve years old, a college student out of home for his school time.
This first digest work of one of the greatest discoveries is signed Daddy. We see with great pleasure that this research was an actual team work honoring equally the two scientists, "Jim" Watson and Daddy. The schematic diagram of the double helix has a beautiful clarity.
On April 2, Watson and Crick submitted the first official text to the professional review Nature, which published it on April 25. The contrast is striking between the enthusiasm of Daddy's letter and the short and careful scientific release, not illustrated, soberly explaining that the fundamental breakthrough of the new theory is the relative position of the chemical elements in the molecule.
Their theory was right, and was soon validated by all biochemists in the world. Daddy's letter is a true treasure in the history of science, unparalleled except perhaps by some letters from Einstein.
Daddy's letter was sold for $ 6.1M from a lower estimate of $ 1M by Christie's on April 10, 2013, lot 1. This document is extraordinary and certainly unique. One of the most important discoveries of our time is announced in a letter to a child before being published in the specialized journals. Emotion takes its place alongside the scientific rigor.

1962 Nobel Prize
Intro
The birth of molecular biology is the result of a multidisciplinary cooperation between chemists, physicists and biologists. The existence of nucleic acids in the cell nuclei had been identified in the nineteenth century. From 1939, advances in micro-radiography X gave hope to understand the structure of these molecules.
Scientists had identified two types of acids, RNA (ribonucleic acid) in the cytoplasm of the cell and DNA (deoxyribonucleic acid) in the chromosomes. They appreciated that these acids held the key to the functioning of life.
Two British laboratories of crystallography worked collaboratively. Francis Crick, assisted by the young US doctor James D. Watson, was at Cambridge. In London, Maurice Wilkins was assisted by Rosalind Franklin who perfected the techniques of observation and realized the radiograms. The untimely cancer of Rosalind Franklin is probably due to an excess of radiation dose.
The single helix of RNA structure and the two strands of DNA were among the first discoveries. In 1953, Watson understood that the shapes of the elements of the two DNA strands were identical although these elements were different. Crick and Watson immediately developed the model of the double helix, which was the biggest breakthrough of all time in the field of life sciences.
Both strands of the helix are connected by regularly spaced links which are always constituted by a pair of chains in two couples of possibilities. When the strands are disjoined, the helix is restructured with organic matter for the creation of the second strand of a new double helix with the same genetic message as the original DNA molecule. Before Crick and Watson, no geometer, no artist had imagined this compact and steady structure.
Crick and Watson knew immediately that they had found the secret of the transmission of information in biological material. With this key, molecular biology soon became a major science, leading to understand cell differentiation and biodiversity.
The letter written by Crick to his young son showed that he was aware of the importance of the discovery. It was sold for $ 6.1M by Christie's in 2013.

Influence on the Advancement of Medicine
The work of Crick and Watson (building on contributions from Wilkins, Rosalind Franklin, and others) fundamentally transformed medicine by establishing the structural basis of DNA, which unlocked the field of molecular biology. This discovery provided the blueprint for how genetic information is stored, replicated, and transmitted, leading to numerous breakthroughs:
Roles in Their Research Team
Crick and Watson formed a close-knit collaborative duo at the Cavendish Laboratory in Cambridge University, working from 1951 to 1953. Their "team" was informal but drew on data from a broader network, including King's College London researchers. They were not experimentalists collecting primary data but rather theoreticians and model-builders who synthesized existing evidence into a coherent structure. Key roles:
Rosalind Franklin's contributions
Introduction
Rosalind Elsie Franklin (1920–1958) was a British chemist and X-ray crystallographer whose pioneering work advanced multiple fields of science. Despite her early death at age 37 from ovarian cancer—possibly linked to prolonged X-ray exposure—she published extensively, including 19 papers on coals and carbons, 5 on DNA, and 21 on viruses. Her contributions were foundational in structural biology, materials science, and virology, though she is most famously associated with the discovery of DNA's structure.
Contributions to Carbon and Coal Research
Early in her career, Franklin studied the physical chemistry of carbon and coal, particularly during World War II when she worked on the porosity and structure of coals for the British Coal Utilisation Research Association. She developed methods to classify coals based on their microstructures, predicting their performance as fuels and materials. This work detailed the structures of graphitizing and non-graphitizing carbons, which formed the basis for developing carbon fibers and heat-resistant materials used in industry. Her findings earned her an international reputation among coal chemists and contributed to advancements in the coking industry.
Contributions to DNA Structure
Franklin's most renowned work occurred at King's College London from 1951 to 1953, where she applied X-ray diffraction techniques to study DNA. She differentiated the A (dry) and B (wet) forms of DNA, solving a key problem that had perplexed researchers, and established that the molecule existed in a helical conformation. By controlling the humidity of DNA samples, she captured high-resolution images, including the famous Photograph 51 in May 1952, taken with her student Raymond Gosling. This image, which required over 100 hours of exposure, revealed the double-helix structure through its X-shaped pattern, providing critical data on DNA's dimensions, density, and base positioning. Her unpublished data and reports were shared with James Watson and Francis Crick (without her full knowledge or consent), enabling them to construct their 1953 model of the DNA double helix. Recent analyses, including overlooked documents from 1953, portray Franklin not as a victim but as an equal contributor who independently grasped the helical structure and its implications for genetic information transfer. She also inferred that DNA played a role in specifying proteins, aligning with the emerging "central dogma" of molecular biology.
Contributions to Virology
After leaving King's College, Franklin joined Birkbeck College in 1953 and shifted to studying viruses using X-ray crystallography. She elucidated the structures of helical viruses like tobacco mosaic virus (TMV) and spherical viruses such as poliovirus. Her work on TMV confirmed its hollow cylindrical structure and the arrangement of RNA within protein subunits, laying the groundwork for structural virology. Collaborating with Aaron Klug (who later won a Nobel Prize), she advanced understanding of virus assembly and infection mechanisms, influencing modern virology and vaccine development.
Legacy and Recognition
Franklin's contributions were pivotal to two Nobel Prizes: the 1962 Physiology or Medicine award to Watson, Crick, and Maurice Wilkins for DNA structure (awarded posthumously ineligible for her), and the 1982 Chemistry award to Klug for virus research influenced by her methods. Debates over credit for DNA highlight issues of gender bias and collaboration ethics in science, with her role often underrecognized until biographies and reevaluations in the late 20th and early 21st centuries. Today, she is celebrated as a trailblazer for women in STEM, with institutions like Rosalind Franklin University named in her honor, and her work continues to underpin advancements in genomics, materials science, and infectious disease research.

The work of Crick and Watson (building on contributions from Wilkins, Rosalind Franklin, and others) fundamentally transformed medicine by establishing the structural basis of DNA, which unlocked the field of molecular biology. This discovery provided the blueprint for how genetic information is stored, replicated, and transmitted, leading to numerous breakthroughs:
- Genetics and Genomics: It enabled the mapping of the human genome (completed in 2003 via the Human Genome Project, which Watson helped initiate), allowing identification of disease-causing genes. This has advanced diagnostics for conditions like cystic fibrosis, sickle cell anemia, and various cancers, facilitating early detection and targeted therapies.
- Biotechnology and Recombinant DNA: Understanding DNA's structure paved the way for techniques like gene cloning, CRISPR-Cas9 gene editing (developed decades later but rooted in their model), and recombinant insulin production (first approved in 1982). These have revolutionized treatments for diabetes, hemophilia, and other genetic disorders.
- Personalized Medicine: Insights into DNA replication and mutations have informed pharmacogenomics, where treatments are tailored to an individual's genetic profile, improving efficacy and reducing side effects in areas like oncology (e.g., drugs targeting specific mutations in BRCA genes for breast cancer).
- Infectious Disease and Vaccines: The model explained viral replication, aiding the development of antiviral drugs and mRNA vaccines (e.g., for COVID-19 in 2020-2021), which rely on manipulating genetic material.
- Broader Impacts: It shifted medicine from symptom-based to molecular-level interventions, contributing to regenerative medicine, stem cell research, and forensic applications like DNA fingerprinting (introduced in the 1980s). Overall, their discovery accelerated the biotech industry, now valued in trillions, and has saved countless lives through improved understanding of heredity, evolution, and disease mechanisms.

They were not experimentalists collecting primary data but rather theoreticians and model-builders who synthesized existing evidence into a coherent structure. Key roles:
- Francis Crick: A physicist by training who transitioned to biology, Crick served as the theoretical anchor. He focused on interpreting X-ray crystallography data (notably from Rosalind Franklin's unpublished Photo 51) to deduce DNA's helical form and base-pairing rules (adenine-thymine, guanine-cytosine). Crick proposed the "central dogma" of molecular biology (DNA → RNA → protein), which explained information flow, though this came post-discovery. His role involved mathematical modeling, hypothesis testing, and ensuring the structure aligned with chemical and physical principles. He was instrumental in writing their seminal 1953 Nature paper.
- James Watson: A young American zoologist influenced by the bacteriophage group, Watson brought biological insights into genetic replication and mutation. He handled much of the physical model-building (using cardboard cutouts and metal pieces) and emphasized the biological implications, such as how the structure allowed for faithful copying during cell division. Watson's enthusiasm drove the partnership, and he facilitated access to key data through informal channels (e.g., from Wilkins). Post-discovery, he advocated for applying the model to genetics, later directing the Human Genome Project.

The knowledge of the physico-chemical functioning of life made its breakthroughs in the mid-twentieth century helped of course by the X-rays but also by the improvement of electricity and electronics.
Alan Hodgkin and Andrew Huxley are biophysicists and more exactly electrophysiologists. The new technique of the voltage clamp allows them to measure the electric signal across the membrane of a nerve cell.
The sciatic nerve of the frog did not allow measurements in a sufficient accuracy. Working in association with the marine biology laboratory of Plymouth in England, they use in their experiments the largest known axon in the animal reign, measuring 1 mm in diameter, used by the squid to elicit a quick reaction to a threat.
The two researchers can then model the electrical behavior of the neuron. This fruitful advance will have a considerable impact on the knowledge and healing of several nerve diseases and will enable to raise a model of the transmission of nerve inputs to the muscular system. The existence of ion channels in cell membranes will be confirmed by others much later, completing the description of the nervous cell.

Alan Lloyd Hodgkin, a British physiologist and biophysicist, shared the 1963 Nobel Prize in Physiology or Medicine with Andrew Huxley and John Eccles for their groundbreaking discoveries on the ionic mechanisms underlying nerve impulses. Their work focused on how sodium and potassium ions move across nerve cell membranes to generate and propagate action potentials, the electrical signals that enable communication within the nervous system.
Hodgkin's contributions, particularly through the Hodgkin-Huxley model developed in the late 1940s and early 1950s, provided a mathematical and experimental framework for understanding voltage-gated ion channels and the kinetics of nerve excitation. This model revolutionized neuroscience by explaining the fundamental process of nerve conduction at a molecular level, replacing earlier vague theories with precise, quantifiable predictions that could be tested experimentally.
His influence on the advancement of medicine has been profound and enduring:

- Foundation for Neurophysiology: The insights from Hodgkin's research form the basis for modern understanding of how neurons function, influencing fields like neurology, psychiatry, and anesthesiology. For instance, it underpins knowledge of how local anesthetics block sodium channels to prevent pain signals.
- Drug Development and Treatments: By elucidating ion channel behavior, his work enabled the development of medications targeting these channels, such as anti-epileptic drugs (e.g., those affecting sodium channels to stabilize neuronal firing) and treatments for cardiac arrhythmias, where similar ionic mechanisms apply to heart muscle cells.
- Broader Scientific Legacy: The Hodgkin-Huxley model inspired subsequent Nobel Prize-winning research, including Erwin Neher and Bert Sakmann's patch-clamp technique for studying single ion channels (1991) and Roderick MacKinnon's structural studies of ion channels (2003). It also advanced computational neuroscience, allowing simulations of neural networks that aid in researching disorders like Alzheimer's, Parkinson's, and multiple sclerosis.
1993 Kary Mullis Nobel Prize in Chemistry
2016 SOLD for $ 670K by Bonhams
Life exists because the chains of the DNA molecule have the capability to replicate. The discovery of the double helix structure by the team of crystallographers of Crick and Watson in 1953 was followed as early as 1956 by the discovery of the catalyst by a biochemist, Kornberg.
The molecular phenomena are too small to be studied individually but the challenge is immense. Genetic defects or viral attacks would be best countered if their mechanisms were modeled on the scale of the chain sequence.
The early tests for the replication in vitro of complete DNA sequences are discouraging by their processing time and their low yield. Chemists take control in their turn of that problem. In 1982, a publication by Dr. Kary Mullis working for Cetus company provides the solution, identified as PCR (Polymerase Chain Reaction).
Once the chain carrying the property to be analyzed is isolated, it is put in the presence of a nourishing primer and subjected to successive cycles of heating and cooling. The reaction is fast and the population growth is exponential. The invention of Mullis is intuitive. His great merit is to have proved the correctness of his concept by developing the appropriate machine. The impact on genetic engineering is immediate.
Mullis received the 1993 Nobel Prize in Chemistry, shared with the biochemist Michael Smith.
On February 14, 2016, Bonhams sold in one lot for $ 670K from a lower estimate of $ 450K the Nobel medal of Dr. Mullis along with his Nobel diploma, a copy of his lecture and several other documents, lot 93.

1993 Nobel prize to Mullis. Define his influence on the advancement of Chemistry.
Kary Mullis was awarded the Nobel Prize in Chemistry in 1993 for his invention of the polymerase chain reaction (PCR), a groundbreaking technique that allows for the rapid amplification of specific DNA segments. This method, conceived by Mullis in 1983 while working at Cetus Corporation, fundamentally transformed the field of chemistry by enabling scientists to produce millions of copies of a single DNA molecule from minute samples, overcoming previous limitations in DNA manipulation and analysis.
PCR's influence on the advancement of chemistry is profound and multifaceted. At its core, it revolutionized DNA-based chemistry by providing a simple, efficient way to amplify genetic material using heat-stable enzymes (like Taq polymerase), oligonucleotides, and repeated cycles of heating and cooling. This innovation shifted DNA research from being labor-intensive and limited by sample size to highly scalable and precise, accelerating progress in molecular biology and biochemistry. For instance, it made possible the sequencing of the human genome, the study of ancient DNA from fossils (such as a 40,000-year-old mammoth), and the development of recombinant DNA technologies.
Beyond pure chemistry, Mullis's work spurred exponential growth in related fields, including:

1993 Nobel prize to Mullis. Define his influence on the advancement of Chemistry.
Kary Mullis was awarded the Nobel Prize in Chemistry in 1993 for his invention of the polymerase chain reaction (PCR), a groundbreaking technique that allows for the rapid amplification of specific DNA segments. This method, conceived by Mullis in 1983 while working at Cetus Corporation, fundamentally transformed the field of chemistry by enabling scientists to produce millions of copies of a single DNA molecule from minute samples, overcoming previous limitations in DNA manipulation and analysis.
PCR's influence on the advancement of chemistry is profound and multifaceted. At its core, it revolutionized DNA-based chemistry by providing a simple, efficient way to amplify genetic material using heat-stable enzymes (like Taq polymerase), oligonucleotides, and repeated cycles of heating and cooling. This innovation shifted DNA research from being labor-intensive and limited by sample size to highly scalable and precise, accelerating progress in molecular biology and biochemistry. For instance, it made possible the sequencing of the human genome, the study of ancient DNA from fossils (such as a 40,000-year-old mammoth), and the development of recombinant DNA technologies.
Beyond pure chemistry, Mullis's work spurred exponential growth in related fields, including:
- Biotechnology and industry: PCR fueled the biotech boom, creating a multi-billion-dollar market through applications in drug design, genetic engineering, and diagnostics. It enabled small teams to manipulate DNA directly, democratizing access to advanced genetic tools and contributing to the rise of startups in the sector.
- Medicine and diagnostics: The technique became essential for detecting pathogens, genetic disorders, and cancers, as seen in its role as the gold standard for COVID-19 testing. It also advanced personalized medicine by allowing rapid analysis of genetic variations.
- Forensics and paleontology: PCR's ability to amplify trace DNA transformed criminal investigations (e.g., identifying suspects from tiny samples) and enabled the study of extinct species' genomes, expanding the scope of bioorganic chemistry.
