1687 Principia by NEWTON
Forerunners
Johannes Kepler, born in a modest family, had an early interest in astronomy. He endeavored to help his mother accused of witchcraft. His intuition that astrology meets exact mechanisms that can be described in models made him the first modern physicist.
Kepler understood that the heliocentric model of Copernicus was not enough. The demonstration proposed by Copernicus is admirable but is indeed nothing more than a calculation.
Kepler had a poor eyesight and was not himself an astronomer. He joined the team of Tycho Brahe in Prague. Kepler used the highly accurate observations made by Brahe while opposing his planetary system that did not explain the orbit of Mars. His own work led him to demonstrate that the orbit of a planet is not circular but elliptical.
He now sees the sun as a motor that generates a greater speed when the planet is closer and compares this effect to a magnet. Newton will rely directly on Kepler's results to formulate the law of universal gravitation.
Kepler prepares from 1600 to 1606 the presentation of his first two laws, summarized above. A dispute with Brahe's heirs suspends the publication until 1609. The title, Astronomia nova, shows Kepler's rightful ambition to offer a completely new approach in this domain. Astrophysics was indeed born with this book.
The printed quantity is very small : the author is an employee of the Emperor Rudolph II and the edition is done without a commercial intent. To compensate for some salary delays, Kepler obtains the right to sell a few copies.
Copies of Astronomia Nova were sold for £ 212K by Sotheby's on May 20, 2014, and fot $ 230K i by Christie's on June 17, 2008.
The next scientific wonder is the development of abstract mathematics with Napier's theory of the logarithms, published in 1614, simplifying the multiplication by establishing a corresponding table which can be used by addition.
The second law of Kepler, about the speed of the planets, was better characterized by him as the fact that a line segment between a planet and the sun sweeps out equal areas during equal intervals of time. He will be one of the earliest scientific users of the logarithms. His third law, known as the harmonic law, defines a relationship between the distance of planets from the Sun, and their orbital periods.
On October 25, 2022, Bonhams sold for $ 880K an autograph working scientific manuscript in Latin by Johannes Kepler, in four pages 22 x 34 cm, lot 1009.
That early trial of using logarithms for calculating the movements of the planets is densely written with many deletions and emendations. Its terminus post quem is 1618 when Kepler got a copy of Napier's tables. The terminus ante quem is the publishing by Kepler of his third law in 1619. The manuscript narrated above was published by him in 1620.

Isaac Newton : Influence on the advancement of Physics, Astronomy and overall on Science and Knowledge. Psychological evaluation.
Isaac Newton's Influence on the Advancement of Physics, Astronomy, and Overall Science and Knowledge
Isaac Newton (1643–1727) stands as one of the most pivotal figures in the history of science, fundamentally reshaping our understanding of the physical world through his groundbreaking work in mathematics, physics, optics, and astronomy. His contributions during the Scientific Revolution laid the foundations for classical mechanics and modern scientific inquiry, influencing fields far beyond his era and enabling advancements in technology, engineering, and cosmology that persist today.
Contributions to Physics
Newton's most renowned work, Philosophiæ Naturalis Principia Mathematica (commonly known as the Principia), published in 1687, introduced his three laws of motion, which became the bedrock of classical physics. These laws are:
In optics, Newton's 1704 book Opticks demonstrated that white light is composed of a spectrum of colors through prism experiments, laying the groundwork for spectral analysis and modern understanding of light as a wave-particle phenomenon. He also invented the reflecting telescope in 1668, which minimized chromatic aberration and advanced observational tools in physics and astronomy.
Contributions to Astronomy
Newton's gravitational theory derived Kepler's laws of planetary motion from first principles, confirming heliocentrism and explaining the precession of equinoxes, lunar orbits, and satellite dynamics. By applying his laws to Jupiter's moons and Earth's Moon, he showed that the same force governing apples falling on Earth holds planets in orbit around the Sun. This unification eradicated doubts about the Solar System's structure and enabled predictions of celestial events, such as Halley's Comet's return. His reflecting telescope design improved astronomical observations, contributing to later discoveries in stellar dynamics and galactic behavior.
Newton's work extended to calculating the speed of sound and the density of air, influencing astrophysics and planetary science. His model of the universe was more elegant and consistent than predecessors, fostering a mechanistic worldview that propelled astronomy forward.
Broader Impact on Science and Knowledge
Newton co-invented infinitesimal calculus (independently of Leibniz), providing tools for solving problems in rates of change, integrals, and differential equations—essential for physics, engineering, and economics. His emphasis on empirical evidence and mathematical rigor refined the scientific method, shifting science from philosophical speculation to quantitative experimentation. This approach catalyzed the Enlightenment, inspiring figures like Voltaire and Kant, and established Newton as the exemplar of modern science.
Overall, Newton's ideas revolutionized knowledge by demonstrating that natural phenomena could be explained through universal laws, influencing everything from space exploration to quantum mechanics. His legacy is often summarized as having contributed more to science than any other individual, ushering in an era where observation and mathematics became the pillars of human understanding.
Psychological Evaluation of Isaac Newton
Posthumous psychological assessments of Newton are inherently speculative, based on historical accounts, letters, and biographical analyses rather than clinical diagnoses. However, evidence from contemporaries and modern analyses points to a complex personality marked by insecurity, introversion, and episodes of mental distress, possibly exacerbated by environmental factors like mercury exposure from his alchemical experiments. Sources vary in their interpretations, with some attributing symptoms to bipolar disorder, depression, or schizophrenia, while others emphasize mercury poisoning or neurotic traits stemming from childhood trauma.
Newton was described as deeply introverted, secretive, and protective of his privacy, often avoiding social interactions and forming few close relationships. He exhibited low self-esteem, egotism, dominance, and paranoia, fearing theft of his ideas or criticism from rivals like Robert Hooke or Leibniz. As a child, he was solitary, preferring inventions over play, and his mother's remarriage and separation from him at age three likely contributed to lifelong insecurity and trust issues.
A major episode occurred in 1692–1693, often called a "nervous breakdown" or "madness," lasting about 18 months. Symptoms included severe insomnia, poor digestion, loss of appetite, memory problems, delusions of persecution (e.g., believing friends like John Locke and Samuel Pepys were conspiring against him), paranoia, and irrational accusations. He experienced violent temper outbursts, apathy, and withdrawal from friendships, including a strained relationship with Nicolas Fatio de Duillier. Explanations differ:

Newton's most renowned work, Philosophiæ Naturalis Principia Mathematica (commonly known as the Principia), published in 1687, introduced his three laws of motion, which became the bedrock of classical physics. These laws are:
- Law of Inertia: A body remains at rest or in uniform motion unless acted upon by an external force.
- Law of Acceleration: The change in motion is proportional to the force applied (F = ma).
- Law of Action-Reaction: For every action, there is an equal and opposite reaction.
In optics, Newton's 1704 book Opticks demonstrated that white light is composed of a spectrum of colors through prism experiments, laying the groundwork for spectral analysis and modern understanding of light as a wave-particle phenomenon.

He experienced violent temper outbursts, apathy, and withdrawal from friendships, including a strained relationship with Nicolas Fatio de Duillier. Explanations differ:
- Mercury Poisoning: Hair analysis from the 1970s showed elevated mercury (up to 40 times normal) and lead levels, consistent with his alchemical pursuits involving toxic substances. Symptoms like tremor, confusion, paranoia, and memory loss align with chronic mercury poisoning (mercurialism), which some argue caused or worsened his 1693 episode rather than inherent mental illness.
- Bipolar Disorder: Newton showed manic phases (intense, sleepless productivity leading to major discoveries in his 20s) alternating with depressive lows, including suicidal thoughts, anxiety, and sadness documented in his notebooks. His high-strung nature and brooding suggest neuroticism, where overthinking fueled both creativity and unhappiness.
- Other Possibilities: Some propose schizophrenia (hallucinations, delusions, paranoia) or autism (social difficulties, obsessive focus), but these are less supported; one analysis rejects Asperger's syndrome in favor of childhood-induced vulnerability. Depression or melancholia is frequently cited, with grandiose elements in his self-perception (e.g., feeling chosen by God).

Isaac Newton was the most brilliant scientific innovator of all time. Late in his life he laid down the rules that had guided his unprecedented method. One of these rules summarizes in a simple sentence how he created the modern physics : to the same natural effects we must, as far as possible, assign the same causes.
One of his outstanding skills was to develop mathematical methods of high complexity to analyze and support his own physical theories. Even before he was 30, he compared the motion of the planets and the fall of the bodies. Essentially preoccupied with his own understanding of the mechanism of the universe, he published reluctantly.In 1684 in London, the scientists of the Royal Society challenged themselves to find the mathematical formulation of the law of motion of the planets described by Kepler. All failed. Halley visits Newton in Cambridge. He is stunned : Newton knows the solution but has lost his calculation notes. The orbital movement of a celestial body is an ellipse whose position of the other body is one of the foci.
The scientific stake is highly important and Halley manages to persuade Newton to disclose in their entirety his results concerning the law of universal gravitation. Edited and financed by Halley, Newton's Latin book entitled Philosophiæ Naturalis Principia Mathematica is published in 1687 with the imprimatur of the Royal Society.
The book is difficult in the opinion of the author himself and the circulation probably did not exceed 300 copies but it is of such scientific importance that Halley and Newton took care of organizing their sale through booksellers. One of them named Samuel Smith is more specifically entrusted to the supply onto the Continent and receives about 50 copies for that purpose.
On December 14, 2016, Christie's sold one of the Smith 'Continental' presentation copies of the Principia for $ 3.7M from a lower estimate of $ 1M, lot 167. It is bound in its original unrestored morocco with gold and red inlays. The recipient is not identified.

1694 Autograph Notes by Newton and Gregory
2021 SOLD for £ 1.7M by Christie's
The quest for the divine truth is the passion of Isaac Newton. He appreciates that his original edition of the Principia in 1687 still has some unanswered questions. He does not want being disturbed by outsiders. The book is in Latin and not in vernacular so that only great minds will comprehend it. Somebody said : "There goes a man who has written a book neither he nor anyone else can understand".
David Gregory was one of the happy few who were skilled to construct on the Principia. A professor of mathematics at the University of Edinburgh, he was 17 years younger than Newton. He was the first to lecture on the Principia and began communicating with Newton. In 1691 Newton managed to have Gregory elected to the Savilian chair of astronomy at the University of Oxford.
In May 1694 Gregory visited Newton in Cambridge in a six day working session based on the proposed revisions to the Principia. Their combined autograph manuscripts are heavily revised working documents based on the texts under discussion from throughout the Principia.
A scrap of paper 22 x 19 cm escaped for an unknown reason the deposit of Gregory's papers at the Royal Institution in the 1860s. These one and a half pages in Latin include 39 lines in Newton’s hand, alongside 14 lines and two diagrams by Gregory. They deal with three topics : the force acting in the compression of liquids, the orbit of the comets, the build of conic figures on centripetal forces.
This unpublished scientific draft was sold for £ 1.7M from a lower estimate of £ 600K by Christie's on July 8, 2021, lot 22. Please watch the video shared by the auction house. The tweets illustrate both sides of the paper.

1704 Opticks by Newton
2015 SOLD for $ 1.33M by Sotheby's
In 1666 Isaac Newton aged 24 is working on improving the optics of the telescopes. His observation that the generation of the spectrum is related to the physical properties of light and not to those of the prism is one of the most important scientific advances of his time. He irrefutably demonstrates it by recomposing the white light though a second prism.
In 1672, he manages to suppress the chromatic aberration in the telescopes and reveals his findings at the Royal Society which publishes his lecture in its Philosophical Transactions.
The great scientist had a difficult temperament and did not accept contradiction. Robert Hooke, who had considered before Newton a wave property of light, is challenging some elements. The hatred between the two physicists is irremediable. Newton refuses to publish his book all along Hooke's lifetime.
Fortunately, Newton also has friends such as Edmund Halley who helps him to publish in 1687 his seminal book on the use of mathematics to model the gravitational properties of matter, the Philosophiae Naturalis Principia Mathematica.
Opticks is finally printed and released in London in 1704, curiously without the author's name, the year after the death of Hooke. Newton added two discussions on curvilinear figures, in order to establish his priority over an ongoing work by Leibniz.
The copy of Opticks presented by Newton to Halley was sold for $ 1.33M from a lower estimate of $ 400K by Sotheby's on December 4, 2015, lot 918. It is not dedicated but Halley wrote on the inside title page: "Luceo. Ex dono doctissimi authoris". Luceo, which does not mean anything in Latin, is a burst of enthusiasm based on Lux.

1745-1749 Sistème du Monde selon Neuton by Mme du Châtelet
2012 SOLD for € 960K by Christie's
Helped by Maupertuis and Clairaut, the Marquise du Châtelet is able to understand and comment on Newton and Leibniz. In their château de Cirey, the marquis admires the exceptional intelligence of his wife and closes his eyes on her loves.
In 1734 Voltaire is disgraced. The Marquise lodges him in Cirey. She is 27 years old. The philosopher learns from his mistress the mathematics and physics that he had largely neglected until then.
The Marquise is a tireless worker. Her manuscripts, often written by secretaries and extensively reworked by her, surfaced a few years ago in an attic. Important pieces were sold by Christie's on October 29, 2012. A call for donations had been issued for an acquisition by the French State and 1400 researchers from around the world had signed a petition for a pre-emption. Both moves were unsuccessful because of the high prices that were expected.
The top lot was a set of 35 workbooks prepared from 1745 to 1749 by Madame du Châtelet for the didactic abstracts accompanying her translation of Newton's Principia Mathematica. Estimated € 400K, it was acquired in that sale for € 960K by the Musée des Lettres et Manuscrits de Paris which had immediately communicated its commitment to exhibit it to the public.
The museum was managed by Aristophil. In the same sale, Aristophil had anonymously acquired 8 lots of manuscripts by the Marquise, 2 lots of manuscripts by Voltaire on Newton and a portrait of the Marquise attributed to Marie-Anne Loir.
These lots were sold on November 19, 2018 by OVA, the company in charge of the legal dispersion of the Aristophil collections. The auction was operated by Artcurial. The abstracts of the Principia were sold for € 510K, lot 689.

Influence on the Advancement of Physics, Astronomy, and Overall Science and Knowledge
Albert Einstein (1879–1955) was a German-born theoretical physicist whose groundbreaking work revolutionized multiple scientific disciplines. His theories not only reshaped fundamental understandings of the universe but also laid the groundwork for technologies and concepts that permeate modern life. Below, I outline his key contributions, focusing on physics, astronomy, and broader impacts on science and human knowledge.
Contributions to Physics
Einstein's most transformative ideas emerged in 1905, his "annus mirabilis," when he published four seminal papers while working as a patent clerk. These included explanations of the photoelectric effect, Brownian motion, special relativity, and mass-energy equivalence (E=mc²). The photoelectric effect, for which he won the 1921 Nobel Prize in Physics, demonstrated that light behaves as particles (photons), providing a cornerstone for quantum mechanics. This challenged classical wave theories and influenced fields like quantum theory, where Einstein also contributed to early developments, though he later critiqued its probabilistic nature with his famous "God does not play dice" remark.
His theory of special relativity (1905) unified space and time into spacetime, establishing that the laws of physics are the same for all non-accelerating observers and that the speed of light is constant. This led to E=mc², linking mass and energy, which underpins nuclear physics and energy production. In 1915, he expanded this with general relativity, redefining gravity as the curvature of spacetime caused by mass. General relativity predicted phenomena like time dilation, gravitational waves (confirmed in 2015), and the bending of light around massive objects, confirmed during a 1919 solar eclipse. These theories resolved inconsistencies in Newtonian physics and enabled advancements in particle physics, cosmology, and even everyday technologies like GPS, which accounts for relativistic effects.
Contributions to Astronomy
Einstein's work profoundly influenced astronomy by providing tools to understand cosmic phenomena. General relativity predicted gravitational lensing, where massive objects bend light, allowing astronomers to observe distant galaxies and dark matter. It also forecasted black holes, relativistic jets from them, and the expansion of the universe—ideas that shaped modern cosmology and were validated by observations like those from the Hubble Space Telescope. His equations enabled the study of the universe's evolution, from the Big Bang to gravitational waves detected by LIGO. Astronomy shifted from descriptive to predictive science partly due to Einstein, influencing discoveries in exoplanets, neutron stars, and cosmic microwave background radiation.
Overall Impact on Science and Knowledge
Einstein's legacy extends beyond specific fields, fostering a paradigm shift in scientific inquiry. He demonstrated how mathematics could reveal nature's laws, blending physics with geometry in general relativity. His work bridged classical and quantum realms, inspiring unified theories and advancements in fields like chemistry (via quantum mechanics) and engineering (nuclear power, lasers from photoelectric insights). Philosophically, he challenged deterministic views, emphasizing relativity in observation and the interconnectedness of matter, energy, space, and time. As a cultural icon, Einstein symbolized intellectual curiosity, influencing education, ethics in science (e.g., his warnings on atomic weapons), and interdisciplinary approaches. His ideas permeated knowledge systems, from epistemology to technology, making abstract concepts accessible and driving innovations like semiconductors and space exploration.
Psychological Evaluation
Evaluating Einstein's psychology retrospectively is speculative, as no formal diagnoses were made during his lifetime, and modern criteria for neurodivergence evolved later. Insights come from biographies, brain studies, and expert analyses, focusing on his cognitive style, social traits, and brain anatomy.
Einstein's brain, preserved after his 1955 death, showed atypical features: enlarged parietal lobes linked to visuospatial and mathematical abilities, and an extraordinary prefrontal cortex potentially supporting his abstract thinking and creativity. These may explain his self-described "associative play" of visual and muscular images in problem-solving, rather than verbal processes. His brain weight was average (age-adjusted around 1,352g), but unusual sulcal patterns suggested neurological reorganization for higher cognition.
Speculations about neurodivergence include autism spectrum disorder (ASD) or Asperger's syndrome, based on traits like late speech (he spoke fluently around age 9), intense focus on interests, social awkwardness, bluntness, and preference for solitude. Experts like psychiatrist Michael Fitzgerald and autism researcher Simon Baron-Cohen noted overlaps between ASD genes and creativity, suggesting Einstein's "social phobia" and nonconformity aligned with this.

Influence on the Advancement of Physics, Astronomy, and Overall Science and Knowledge
Albert Einstein (1879–1955) was a German-born theoretical physicist whose groundbreaking work revolutionized multiple scientific disciplines. His theories not only reshaped fundamental understandings of the universe but also laid the groundwork for technologies and concepts that permeate modern life. Below, I outline his key contributions, focusing on physics, astronomy, and broader impacts on science and human knowledge.
Contributions to Physics
Einstein's most transformative ideas emerged in 1905, his "annus mirabilis," when he published four seminal papers while working as a patent clerk. These included explanations of the photoelectric effect, Brownian motion, special relativity, and mass-energy equivalence (E=mc²). The photoelectric effect, for which he won the 1921 Nobel Prize in Physics, demonstrated that light behaves as particles (photons), providing a cornerstone for quantum mechanics. This challenged classical wave theories and influenced fields like quantum theory, where Einstein also contributed to early developments, though he later critiqued its probabilistic nature with his famous "God does not play dice" remark.
His theory of special relativity (1905) unified space and time into spacetime, establishing that the laws of physics are the same for all non-accelerating observers and that the speed of light is constant. This led to E=mc², linking mass and energy, which underpins nuclear physics and energy production. In 1915, he expanded this with general relativity, redefining gravity as the curvature of spacetime caused by mass. General relativity predicted phenomena like time dilation, gravitational waves (confirmed in 2015), and the bending of light around massive objects, confirmed during a 1919 solar eclipse. These theories resolved inconsistencies in Newtonian physics and enabled advancements in particle physics, cosmology, and even everyday technologies like GPS, which accounts for relativistic effects.
Contributions to Astronomy
Einstein's work profoundly influenced astronomy by providing tools to understand cosmic phenomena. General relativity predicted gravitational lensing, where massive objects bend light, allowing astronomers to observe distant galaxies and dark matter. It also forecasted black holes, relativistic jets from them, and the expansion of the universe—ideas that shaped modern cosmology and were validated by observations like those from the Hubble Space Telescope. His equations enabled the study of the universe's evolution, from the Big Bang to gravitational waves detected by LIGO. Astronomy shifted from descriptive to predictive science partly due to Einstein, influencing discoveries in exoplanets, neutron stars, and cosmic microwave background radiation.
Overall Impact on Science and Knowledge
Einstein's legacy extends beyond specific fields, fostering a paradigm shift in scientific inquiry. He demonstrated how mathematics could reveal nature's laws, blending physics with geometry in general relativity. His work bridged classical and quantum realms, inspiring unified theories and advancements in fields like chemistry (via quantum mechanics) and engineering (nuclear power, lasers from photoelectric insights). Philosophically, he challenged deterministic views, emphasizing relativity in observation and the interconnectedness of matter, energy, space, and time. As a cultural icon, Einstein symbolized intellectual curiosity, influencing education, ethics in science (e.g., his warnings on atomic weapons), and interdisciplinary approaches. His ideas permeated knowledge systems, from epistemology to technology, making abstract concepts accessible and driving innovations like semiconductors and space exploration.
Psychological Evaluation
Evaluating Einstein's psychology retrospectively is speculative, as no formal diagnoses were made during his lifetime, and modern criteria for neurodivergence evolved later. Insights come from biographies, brain studies, and expert analyses, focusing on his cognitive style, social traits, and brain anatomy.
Einstein's brain, preserved after his 1955 death, showed atypical features: enlarged parietal lobes linked to visuospatial and mathematical abilities, and an extraordinary prefrontal cortex potentially supporting his abstract thinking and creativity. These may explain his self-described "associative play" of visual and muscular images in problem-solving, rather than verbal processes. His brain weight was average (age-adjusted around 1,352g), but unusual sulcal patterns suggested neurological reorganization for higher cognition.
Speculations about neurodivergence include autism spectrum disorder (ASD) or Asperger's syndrome, based on traits like late speech (he spoke fluently around age 9), intense focus on interests, social awkwardness, bluntness, and preference for solitude. Experts like psychiatrist Michael Fitzgerald and autism researcher Simon Baron-Cohen noted overlaps between ASD genes and creativity, suggesting Einstein's "social phobia" and nonconformity aligned with this. ADHD traits, such as disorganization and forgetfulness amid insightfulness, have also been proposed. Claims of dyslexia or dyspraxia are debated; while he struggled in rigid schooling, evidence points more to motivational blocks than neurological deficits in language processing. Psychodynamic perspectives, drawing from Freud, suggest Einstein sublimated unconscious drives into scientific pursuits, with his ego balancing id impulses and superego norms.

1913 Relativity by Einstein and Besso
2021 SOLD for € 11.7M by Aguttes-Perrine
Albert Einstein early appreciated that physics is a complex inter-relation between the basic concepts of light, electricity, energy, inertia, mass. He therefore brings a modern view to Newton's works.
In physics it is not uneasy to propose theories and equations. None of them is valid until it is verified by an experience.
There was a discrepancy in the application of Newton's universal gravitation theory : the orbit of Mercury, the nearest planet to the sun, is not perfectly elliptic. The tiny discrepancy is 43 seconds of arc per century at the perihelion.
In June 1913 in Zurich, Einstein and his lifelong friend Michele Besso manage a working session on the Mercury issue. Einstein's unprecedented intuition is that the gravity must be distorted by the rotation.
The two friends create and test equations in a method of trial and error. None of them matches the expected result of 43 seconds per century. After some additions in early 1914, Besso keeps their working notes.
This autograph draft document is made of 54 pages on 37 loose sheets 21 x 27 cm in equal parts by Einstein and Besso. It was sold for $ 560K by Christie's on October 4, 2002, lot 81. Coming from the Aristophil judicial liquidation, it was sold for € 11.7M from a lower estimate of € 2M by Aguttes et Perrine supported by Christie's on November 23, 2021, lot A. Please watch the video prepared by Christie's.
Einstein is persistent. He manages to refine the parameters and establish the suitable "Einstein field equations", thus releasing in 1915 a refined theory of gravitation known as the general relativity which is still today the basic of cosmology.

1939 Letter to President Roosevelt
2024 SOLD for $ 3.9M by Christie's
In January 1939, Niels Bohr, visiting the United States, informed physicists of the control of the fission of the uranium atom by the Berlin team. The Germans are ahead of the rest of the world on the way to the atomic bomb. Their result is confirmed by new experiments in Paris, Columbia University and Princeton.
Physicists are trying to warn the government. Fermi fails. Szilard rightly considers that the message must be carried by an illustrious figurehead. He chooses Einstein. This project resulted in two slightly different typed letters, dated August 2, 1939, which Szilard prepared and had Einstein signed for communication to President Roosevelt.
Now they must capture the president's attention. Szilard has an ally, Alexander Sachs, who had been a close associate of Roosevelt. Sachs is suspicious of Einstein's pacifist positions and would have preferred Lindbergh but the contact with the aviator had failed.
An appointment is finally made in October by Sachs to deliver Einstein's letter to Roosevelt. The President, annoyed at first, suddenly understands what is at stake : they must prevent the Germans from blowing everything up. He creates a Board that will lead to the Manhattan Project, and sends Einstein a letter of thanks.
The other letter signed by Einstein on August 2, 1939 had been retained by Szilard. Accompanied by Einstein's autograph cover letter in German to Szilard, it was sold by Christie's for $ 2.1M by Christie's on March 27, 2002, lot 161, and for $ 3.9M on September 10, 2024, lot 6 in the sale of the Paul G. Allen collection. Please watch the video shared by the auction house.
Einstein was never told about the Manhattan Project. After the destruction of Hiroshima, he will declare that his letter to Roosevelt was the great mistake of his life. He had not understood in time that the Germans did not really have the skills to develop atomic bombs.

The Einstein-Szilard letter is one of the most influential letters written in the 20th century, leading to the birth of the nuclear age. Here, Senior Specialist Peter Klarnet dives into this document that influenced Paul G. Allen.
- The X post from Christie's discusses the Einstein-Szilard letter, a pivotal document in the 20th century that influenced the development of nuclear technology, specifically leading to the Manhattan Project and the birth of the nuclear age. This letter, written by Albert Einstein and dictated by Leo Szilard, warned President Franklin D. Roosevelt about the potential of nuclear fission for both energy and weaponry, urging action to prevent Nazi Germany from developing atomic bombs first.
- The letter's significance is highlighted by its role in prompting Roosevelt to establish research into nuclear fission, which eventually led to the creation of the Manhattan Project. This project, under the direction of Robert Oppenheimer, was a massive, secretive endeavor costing $2 billion, aimed at developing the first atomic bombs. The letter's impact extended beyond immediate military applications, fundamentally changing how science was funded and conducted, and unleashing technological advancements that indirectly influenced various fields.
- The post also notes the rarity and historical value of the letter, with only two copies ever produced, one of which is preserved at the Franklin D. Roosevelt Library, and the other offered at a Christie's auction as part of Paul G. Allen's collection. This auction, part of the "Gen One: Innovations from the Paul G. Allen Collection," underscores the letter's enduring influence and its connection to broader scientific and technological developments, including the "Atoms for Peace" initiative, which promoted peaceful uses of nuclear energy.

1954 letter to Gutkind
2018 SOLD for $ 2.9M by Christie's
Alchemy sought a relationship between all things. Newton had relied on mathematics in his quest for the philosopher's stone. By dissociating space and time, he had triggered the modern science.
Albert Einstein was born into a Jewish family without religious beliefs. After a very short mystical phase, he rejects in his turn the Biblical scriptures. Newton had not gone far enough : Einstein would link space and time. Around 1902 he finds a frame of thought in Spinoza for whom God could not have a material reality nor act a role in our destinies.
Beyond the laws of physics, the ultimate truth will never be reached. We may attribute the designation of God to this axiom. Einstein is not a pantheist and throughout his life he will state that he is not an atheist. He also follows Spinoza for the social and political consequences of his theories : peoples are equal to each other.
In 1952 the German Jewish philosopher Eric Gutkind publishes a book titled Choose Life: The Biblical Call to Revolt. He sends a copy to Einstein who replies on January 3, 1954 in a private letter.
The concept of a 'chosen' people visibly upsets Einstein although he has managed to remain courteous. He is a Jew who loves his people but the idea of God is a product of human weakness and all religions including Judaism are relics from primitive superstitions.
This two-page autograph letter in German was sold for £ 207K by Bloomsbury on May 15, 2008 and for $ 2.9M by Christie's on December 4, 2018, lot 1. Please watch the video shared by the auction house. Meanwhile in 2012 a transaction on eBay had been reported at a much higher price.

1965 Nobel Medal of Feynman in Physics
2018 SOLD for $ 975K by Sotheby's
Richard Feynman's thinking was original and effective. Reading a commentary by Dirac about the lack of understanding in the theory of quantum electromagnetism, he decides to always rely only on himself for his research while adding a playful dimension. The title of one of his books of reminiscences, Surely you're joking, Mr Feynman !, is significant.
Feynman's method was to use geometry and diagrams rather than developments in mathematical formulas. Highly motivated to share his knowledge, he was the best professor and lecturer in atomic physics, ensuring that his explanations were always clear.
His contributions in theoretical physics are numerous. He solved Dirac's problem by imagining the quantum mechanism of charged particles in rotation, for which he shared in 1965 the Nobel Prize in Physics with Tomonaga and Schwinger. He also made fundamental advances in the model of the helium superfluidity and in the theory of quarks. He was also a visionary, encouraging as early as 1959 the development of nanotechnologies.
On November 30, 2018, Sotheby's dispersed Richard Feynman's research library, including autograph drafts of several lectures. The lot 67, sold for $ 975K, was made of his Nobel medal and diploma along with two documents used during the ceremony.
1965 Nobel prize to Feynman. Define his influence on the advancement of Physics
Richard Feynman was awarded the Nobel Prize in Physics in 1965, shared with Julian Schwinger and Sin-Itiro Tomonaga, for their foundational contributions to quantum electrodynamics (QED), a theory that reconciles quantum mechanics with electromagnetic interactions and has profoundly shaped modern particle physics. This work resolved longstanding inconsistencies in earlier theories, enabling precise predictions of particle behaviors at the subatomic level, such as electron-photon interactions, with unprecedented accuracy.
Feynman's influence extended far beyond QED, revolutionizing multiple areas of physics through innovative tools and concepts that remain central to research today. One of his most enduring legacies is the development of Feynman diagrams, simple visual representations that depict complex particle interactions, making calculations in quantum field theory more intuitive and accessible; these diagrams are now a staple in particle physics textbooks and computations worldwide. He also pioneered the path integral formulation of quantum mechanics, an alternative approach that reframes particle paths as sums over all possible trajectories, influencing fields from quantum computing to statistical mechanics.
In condensed matter physics, Feynman contributed to understanding superfluidity in liquid helium, explaining its frictionless flow at low temperatures, which advanced theories of quantum fluids and earned recognition alongside his other work. His parton model proposed that protons and neutrons consist of smaller constituents (later identified as quarks), laying groundwork for quantum chromodynamics and deep inelastic scattering experiments that transformed high-energy physics. Additionally, Feynman made key advances in weak interactions, such as beta decay, collaborating on theories that unified fundamental forces.
Beyond research, Feynman's impact as an educator and communicator reshaped how physics is taught and perceived. His "Feynman Lectures on Physics," delivered at Caltech and published in the 1960s, demystified complex topics for students and professionals alike, emphasizing conceptual understanding over rote mathematics and inspiring generations of physicists. He popularized science through books like "Surely You're Joking, Mr. Feynman!" and public demonstrations, such as his role in the Challenger shuttle investigation, where he famously illustrated O-ring failure with a simple ice water experiment, highlighting the importance of clear, evidence-based reasoning in science. Overall, Feynman's blend of rigorous innovation, unconventional thinking, and accessible teaching accelerated advancements in theoretical physics while broadening its appeal, making him one of the most influential figures in the field's history.
