1510 The Codex Leicester of Leonardo da Vinci
1994 SOLD for $ 31M by Christie's
From 1475 Leonardo da Vinci recorded everyday all his ideas about the nature of the world in its whole variety, in the form of notes in ancient Italian language illustrated with sketches. In this polygraphic bulimia, he accumulated about 13,000 pages, on double-sided sheets folded in half.
Leonardo is neither a scientist nor an engineer in the modern meaning of these terms. He does not waste his time analyzing the consequences of his theories or conceiving the realization of his inventions. In his swarming of ideas, he could be wonderfully right and naively wrong, and he was certainly unable to distinguish between these two extremes.
For this left-hander, the mirror writing is the way he has found so that his thinking is not slowed down by his hand. The use of numerous abbreviations, which makes these texts extremely difficult to decipher, is consistent with this hypothesis. We will never know how he desired exploiting such a unique mass of informations.
These writings were later assembled into notebooks, identified under the more technical term of codex. The Codex Leicester is the only one remaining in private hands. It was sold by Christie's for $ 5.1M on December 12, 1980 and for $ 31M on November 11, 1994. Between these two sales it was named the Codex Hammer. It was bought by Bill Gates at the last auction. The image is shared by Wikimedia.
The Codex Leicester is made up of 18 double sheets of parchment for a total of 72 pages 22 x 30 cm. It brings together his notes written around 1510 on the theme of the water movements. The author imagines that his ideas could be used for the design of bridges.
His observation on the presence of fossils in the mountains brings an explanation far ahead of his time : they were originally in a seabed which was raised by a geophysical phenomenon. This hypothesis is all the more remarkable since the monotheistic religions of his time do not question the creationism.
In the same notebook, he explains the luminosity of the Moon by the reflection of sunlight on its surface entirely covered with water.
The Codex Leicester (also historically known as the Codex Hammer) is one of Leonardo da Vinci's most important surviving scientific notebooks. It consists of 72 pages (36 folded sheets) of handwritten notes and drawings, composed in mirror script (Leonardo's characteristic right-to-left writing). Dated primarily to around 1508–1510 (with some sections possibly earlier), it reflects his mature investigations into natural phenomena during his later years.
Content
The manuscript focuses on scientific observations and theories, primarily related to water, its movements, and its role in the natural world. Leonardo organizes his thoughts into thematic sections, blending empirical observation, experiments, philosophical speculation, and remarkable foresight.

Content
The manuscript focuses on scientific observations and theories, primarily related to water, its movements, and its role in the natural world. Leonardo organizes his thoughts into thematic sections, blending empirical observation, experiments, philosophical speculation, and remarkable foresight.
Key topics include:
- The nature and motion of water — Leonardo explores how water flows in rivers, eddies, whirlpools, waves, and tides. He describes phenomena like turbulence, erosion, and the behavior of water in pipes or when striking surfaces—ideas that anticipate modern fluid dynamics.
- Hydrology and geology — He discusses why fossils are found on mountains (attributing it to ancient seas rising and falling), river formation, the geological history of Earth, and processes like sedimentation and erosion.
- Astronomy and cosmology — Sections address the "lunar problem" (why the moon appears illuminated even in its dark parts, correctly attributing it to Earthshine—sunlight reflected from Earth).
- Light, optics, and related phenomena — Observations on reflection, refraction, and how water interacts with light.
- Other elements — Brief notes on air, fire, earth, and the four classical elements, plus practical applications like canal engineering and water management.

Born in Vinci, Tuscany, he excelled across painting, drawing, sculpture, anatomy, engineering, architecture, optics, hydrodynamics, and more. His curiosity-driven approach—observing nature meticulously and blending empirical study with imagination—defined his work.
Inspirations
Leonardo drew inspiration from diverse sources that fueled his interdisciplinary genius:
- Nature and the Tuscan landscape — Growing up in rural Vinci, the hills, rivers, and wildlife sparked his lifelong fascination with natural phenomena, from water flow to bird flight and human anatomy.
- Classical antiquity — He studied ancient texts, notably Vitruvius's De Architectura, which influenced his famous Vitruvian Man drawing exploring ideal human proportions based on Roman architectural principles.
- Mentors and contemporaries — As an apprentice in Andrea del Verrocchio's Florence workshop (around 1466–1476), he absorbed technical skills in painting, sculpture, and mechanics. Patron Lorenzo de' Medici exposed him to humanist circles, philosophy, and classical learning. He also engaged with (and rivaled) figures like Michelangelo.
- Scientific observation — Leonardo rejected purely book-based knowledge, prioritizing direct experience—dissecting cadavers, experimenting with optics, and studying motion—to understand the world.
In science and invention:
- Anatomy — Conducted over 30 human dissections, producing highly accurate drawings of muscles, bones, organs, and systems (e.g., heart valves, fetus in womb) that corrected ancient errors and anticipated modern understanding.
- Engineering and mechanics — Designed concepts for machines including ornithopters (flying machines with flapping wings), a helical airscrew (early helicopter prototype), parachute, armored tank, giant crossbow, self-supporting bridge, and diving equipment.
- Hydraulics and geology — Advanced understanding of water flow, erosion, and fossils; proposed accurate explanations for Earth's geological history.
- Optics and other fields — Studied light refraction, camera obscura principles, and even early ideas in astronomy and mathematics.
Sketches of flying machines are showcasing his engineering imagination.
Legacy in Art, Science, and Culture
Leonardo's impact endures profoundly:
- Art — His techniques (sfumato, perspective, emotional realism) influenced the High Renaissance and later movements. The Mona Lisa and Last Supper rank among the most famous and analyzed artworks ever, symbolizing mystery and mastery.
- Science — His notebooks (over 7,000 pages, written in mirror script) reveal prescient insights in anatomy, engineering, and natural philosophy. Though unpublished in his lifetime, they anticipated developments in fields like fluid dynamics, aeronautics, and cardiology.
- Culture — He epitomizes the Renaissance humanist ideal: curiosity, interdisciplinary thinking, and blending beauty with knowledge. Today, he inspires innovators in STEAM (Science, Technology, Engineering, Arts, Math), bio-inspired design, and creative problem-solving. His life represents the pursuit of universal understanding, influencing education, museums, literature (e.g., The Da Vinci Code), and popular views of genius.

1785 Les 120 Journées de Sodome by Sade
Etat Français
When he was a young aristocrat the marquis de Sade believed that anything could be allowed to him within the false stage of his own life. He had no consideration excepted for himself. Increasingly serious sex scandals are emerging in his wake. He is jailed by lettre de cachet in 1777 at the request of his family anxious to protect him from his own "sadistic" perversions.
Transferred in 1784 to the Bastille after a reassignment of the dungeon of Vincennes, Sade is then nobody more than Monsieur le 6 according to the number of his cell. His energy and his hate have not weakened and a liberation is unthinkable. He will never retrieve the freedom of Gilles de Rais or Elisabeth Bathory. He becomes a writer. He wants to be the most impure of all writers.
His first project of book is a catalog of perversions for which he is inspired by the narrative structure of the Decameron. In an abject absence of humanism, girls and boys are toys of torture and death for the sexual pleasure of the masters. The title, Les 120 Journées de Sodome, is an allusion to the 1,001 Arabian Nights.
In October 1785 the draft of the first part is finished. Despite his isolation, Sade fears a confiscation. He copies his text into a tiny and tight writing on 11.3 cm narrow sheets. The set to be kept in a tube is an assembly of 33 sheets glued end to end for a total length of 12.10 m. The top sheets of the roll are inscribed on both sides.
Sade had worked for no result. A few days before the Bastille day of July 14, 1789 he manages through the bars of his cell to add his vociferation within the growing popular discontent. His presence at the Bastille is considered as a threat to security and he is transferred to the hospice of Charenton without being allowed to take anything with him. He will never see again this manuscript of his most atrocious frenzies.
Long considered as lost, the manuscript is the subject of a first edition by a German psychiatrist in 1904. Recovered by a descendant of Sade, it is stolen in 1982 and acquired by a collector of erotic literature, legally under Swiss law and illegally according to French law. Its purchase by the Aristophil company with significant monetary compensation to all involved parties was acclaimed by the press in 2014.
This scroll unique in its theme, format, author and history was a major piece in the liquidation of Aristophil, listed with an estimate of € 4M by Aguttes on December 20, 2017, lot 39. Please watch the video shared by Aguttes. The image below is shared by Wikimedia. It was classified as Trésor national and withdrawn before the sale. It was acquired by the Etat Français in 2021.

1787 US Constitution Committee of Style Draft (with Rufus King autograph)
2026 SOLD for $ 7.4M by Christie's
A copy of the printed working draft of the US Constitution discussed by the Committee of Style had been marked up during the debates by a delegate. It was sold for $ 7.4M from a lower estimate of $ 3M by Christie's on January 23, 2026, lot 214.
Role of the Committee of Style Draft in the Preparation of the U.S. Constitution
The Committee of Style (formally the Committee of Style and Arrangement) was appointed on September 8, 1787, near the end of the Constitutional Convention in Philadelphia. Its task was to revise and polish the text of the Constitution based on the provisions already agreed upon by the delegates after months of debate. The committee consisted of five members: William Samuel Johnson (chair), Alexander Hamilton, James Madison, Rufus King, and Gouverneur Morris.
Gouverneur Morris is widely credited as the primary author of the draft's elegant and concise language—often called the "Penman of the Constitution." The committee condensed the prior resolutions into seven articles and produced a near-final version. Notably, it introduced the iconic Preamble beginning with "We the People of the United States" (replacing an earlier enumeration of the individual states), emphasizing national unity over a loose confederation of states.
On September 12, 1787, the committee's report was presented, and printers John Dunlap and David C. Claypoole produced limited copies for the delegates' use. This printed working draft—the second of only two such drafts created during the Convention (the first was from the earlier Committee of Detail)—allowed delegates to review the text uniformly during final debates from September 12–15. Minor revisions were made, and the final engrossed parchment was signed on September 17, 1787.
This draft represents the Constitution in its almost-final form, capturing the framers' polished vision just before adoption.
Significance of This Specific Print (Lot 214 at Christie's, January 23, 2026)
The document at auction is one of approximately 12 known surviving copies of the Committee of Style's printed draft, making it extraordinarily rare. All other known copies are held in institutional collections (museums, libraries, or archives). This is the first such copy to appear at auction in over 40 years.
It belonged to Rufus King (1755–1827), a Massachusetts delegate (later representing New York) who served on the Committee of Style itself. King's personal copy bears his handwritten annotations, corrections, and suggested alterations, which were incorporated into the final signed version of the Constitution. These markings provide direct insight into the real-time deliberations and last-minute refinements during the Convention's closing days.
As a working document marked up by a key framer, it offers a tangible window into the dynamic process of finalizing the text—far more revealing than clean institutional copies (such as those annotated by George Washington or David Brearley, now in archives). Its provenance ties it directly to the debates, underscoring how delegates like King influenced the document's ultimate wording.
Offered in Christie's "We the People: America at 250" sale (with an estimate of $3–5 million), this artifact is among the most significant Constitutional relics in private hands, illuminating the collaborative yet meticulous crafting of America's founding charter.

1789 Acts of Congress
2012 SOLD for $ 9.8M by Christie's
During the ten years following the Declaration of Independence of the United States, the Congress sets up a code known as the Articles of Confederation to manage the relations between the states. Too idealistic, this first law is a failure.
The founders of the nation are now trying to redefine the delicate balance between the executive and legislative branches while considering also the need for autonomy of each state. Their work is outstanding, since the system defined between 1787 and 1789 is still the foundation of the US law.
George Washington is one of the key figures in this success. On June 22, 2012, Christie's sold for $ 9.8M his personal copy of the main acts of Congress, lot 1. It gathers the Constitution, various acts including the creation of major Executive Departments, and the first draft of twelve articles known as the Bill of Rights for an effective and pragmatic definition of freedoms.
This collection was a working document for the new President. It is also a much valuable autograph : signed on the title page, it includes handwritten notes in the margin of several acts.
These 53 sheets 30 x 19 cm from 1789 are assembled in a binding probably made in the same year. They are in excellent condition.

1864 Emancipation Proclamation
2026 SOLD for $ 6.8M by Christie's
On 22 September 1862, President Lincoln issued an ultimatum to the secessionist states : slavery shall be abolished on January 1 in all states that will not come back into the Union before that date.
At the promised date, January 1, 1863, Lincoln proclaimed an executive order abolishing slavery in the ten states on which he had no control.
Of course, this statement was not sufficient to end the US Civil War. In mid 1864, charity gatherings organized by the US Sanitary Commission are held everywhere to support the Union troops.
The President, always ready for personal commitment, then accepts the project of the authorized edition of the Emancipation Proclamation, one of the initiatives to raise funds.
The document consists of a title and 52 lines of text printed in a single page on a watermarked Whatman paper sheet 55 x 44 cm. The typed field is 37.4 x 17 cm.
The 48 copies edited by Leland and Boker bear the signatures of Abraham Lincoln, of the Secretary of State William Seward and of John Nicolay, private secretary to the President, certifying the authenticity of the other two autographs. They were made available for purchase with a price tag of $ 10 each at the Great Central Sanitary Fair in Philadelphia in June 1864. 27 copies are surviving as of 2025, including 18 kept in institutions.
That strategy confirms that in the mind of Lincoln the end of slavery is a main issue of the Civil War beside saving the Union. Without alienating the states loyal to the Union, it gave such a boost to the slaves that their emancipation had no more obstacles, entering into the constitution through the Thirteenth Amendment in 1865.
A copy was sold for $ 6.8M from a lower estimate of $ 3M by Christie's on January 23, 2026, lot 230.
A full margin copy in fresh condition of the Authorized edition of the Emancipation Proclamation was sold for $ 4.4M by Sotheby's on June 26, 2025, lot 26. This example has been matted, framed and glazed to museum standards. The Abraham Lincoln signature is bold and dark. The counter-signatures by Seward and Nicolay have faded.
One hundred years after the Emancipation, the Kennedy brothers are considering new advances for civil rights. The murder of the President does not slow down the ardor of his brother. In 1964, Robert Kennedy bought at auction at Parke-Bernet a copy of the Emancipation Proclamation signed by Lincoln and Seward. This ex Kennedy document was sold for $ 3.8M on December 10, 2010 by Sotheby's, Parke-Bernet's successor. Please watch the video shared by the auction house.

1865 The Thirteenth Amendment
2025 SOLD for $ 13.7M by Sotheby's
The founding fathers of the USA stated that all men are created equal. The slavery of the Negroes is seen as a disgrace by President Lincoln, not for moral or economic reasons but indeed because it opens up the possibility for a persecution of other minorities.
The thirteenth amendment to the Constitution was a major political achievement by Lincoln. It was not an easy operation, especially as the President did not want to wait for the end of the Civil War.
On 8 April 1864 the Senate voted at 38 against 6 a resolution in favor of the thirteenth amendment, but its embedding into the Constitution also required the approval of the House of Representatives and of 3/4 of the States.
In the House, the required 2/3 majority of voters was impossible to achieve in 1864 but the new elections have strengthened the power of Lincoln. The text was accepted on January 31, 1865 at 119 against 56 plus 8 abstentions after a first negative vote.
The official copy is signed by President Lincoln, Vice President Hamlin representing the Senate and Speaker of the House Colfax. It is kept in the National Archives in Washington DC.
Slavery was abolished in the United States of America in December 1865 when Georgia becomes the 27th state to ratify the thirteenth amendment, eight months after the death of the President.
In the enthusiasm of this joint Congress achievement, some manuscript duplicates are prepared from February 1 on the official paper of the Congress.
The clerk of the House of Representatives had a few copies signed by the three official signers plus the Senate secretary Forney, for their own use plus one for himself. Three examples are surviving.
Somebody managed to have manuscript commemorative copies signed by nearly all the congress members who had voted in favor of the amendment, in addition to the four officials. Lincoln endorsed them as 'Approved'. After six days he stopped providing his signature on new examples.
Nine examples are known to survive with the signatures of 36 to 38 senators plus 109 to 117 representatives.
One of them, a large vellum folio 52 x 39 cm with the signatures through five neatly ruled columns, was sold for $ 720K by Christie's on March 27, 2002, lot 95 and for $ 13.7M by Sotheby's on June 26, 2025, lot 27.
Some copies had the signatures of the senators but not of the representatives. The three known examples were signed at the same time by 36 of the 38 approving senators. One of them is in private hands. This document 55 x 40 cm was sold for $ 2.4M by Sotheby's on May 25, 2016, lot 79.
The thirteenth amendment to the Constitution was a major political achievement by Lincoln. It was not an easy operation, especially as the President did not want to wait for the end of the Civil War.
On 8 April 1864 the Senate voted at 38 against 6 a resolution in favor of the thirteenth amendment, but its embedding into the Constitution also required the approval of the House of Representatives and of 3/4 of the States.
In the House, the required 2/3 majority of voters was impossible to achieve in 1864 but the new elections have strengthened the power of Lincoln. The text was accepted on January 31, 1865 at 119 against 56 plus 8 abstentions after a first negative vote.
The official copy is signed by President Lincoln, Vice President Hamlin representing the Senate and Speaker of the House Colfax. It is kept in the National Archives in Washington DC.
Slavery was abolished in the United States of America in December 1865 when Georgia becomes the 27th state to ratify the thirteenth amendment, eight months after the death of the President.
In the enthusiasm of this joint Congress achievement, some manuscript duplicates are prepared from February 1 on the official paper of the Congress.
The clerk of the House of Representatives had a few copies signed by the three official signers plus the Senate secretary Forney, for their own use plus one for himself. Three examples are surviving.

1888 A Letter with a Drawing of La Maison Jaune by van Gogh
2013 SOLD for $ 5.5M by Christie's
Vincent van Gogh wrote a lot. He thus provided posterity with a direct testimony on his incomparable creativity, on his projects and on his problems.
Arriving in Arles on February 20, 1888, Vincent first stayed at the hotel. The atmosphere was pleasing him and he wanted to install his accommodation and his workshop by the town. He was seduced by a house with yellow walls that he could rent for a low price : it had been vacant for a long time and was fairly decrepit.
His enthusiasm is growing. He set up his workshop in the Maison Jaune, waits for the scheduled connection of town gas which will improve his working conditions, and chooses to invite an artist with whom he feels affinities : Paul Gauguin.
On November 5, 2013, Christie's sold an autograph sheet 13.4 x 20.6 cm for $ 5.5M from a lower estimate of $ 2.5M, lot 16. Please watch the video shared by the auction house.
The back page is the end of a letter, including a praise of Gauguin and wishes of health improvement for Theo. Vincent rarely dated his letters. This document is the fifth page of a letter sent to his brother around September 29, 1888.
The front is a full page ink drawing showing the Maison Jaune with lots of small details and a good animation. This image is a copy of an oil painting he had just made. The artist has not overlooked the long awaited earthworks of the gas companies. He wants to show Theo that his new living environment is ready for an unprecedented artistic adventure.
Gauguin agreed : he knocks on the door of the Maison Jaune on October 24, 1888.

1892 Coubertin's Olympic Address
2019 SOLD for $ 8.8M by Sotheby's
In 1888 the 25-year-old publicist Pierre de Coubertin decides to concentrate all his efforts on the integration of sport into educational systems. Traumatized by the Franco-Prussian War of 1870, he sees sport as a means to ensure peace in the world. The moment is good : the extension of the railroad has favored inter-city sports confrontations in several countries, and the telegraph facilitates the preparations.
With a remarkable open-mindedness, Coubertin compares the progress of sport in several countries. In England, the country of the fair play, football is a team sport practiced in colleges, including Rugby, and the establishment of official rules allows competitions. In Sweden the mental benefit of gymnastics is officially recognized. In the United States, sport opens the way to the practice of collective recreation. He does not like the use of sport for military training in Germany but recognizes its heroic character.
The time is also favorable for meetings of thematic clubs in England and France. They will support the development of the Coubertin project. In 1891 he promulgates a motto : citius, fortius, altius (later modified in its sequence). Coubertin is setting the example : on March 20, 1892 he is the referee in the final of the first French rugby championship.
Taking as a pretext the fifth anniversary of a running club, a conference is organized at the Sorbonne on November 25, 1892, with three speakers. Bourdon and Jusserand tell the history of the sport. Coubertin, entrusted for dealing with modern sport, concludes his speech by proposing the reestablishment of the Olympic Games.
In this seminal address, Coubertin's vision is universal. The most developed nations will help the others. It is a matter of practicing sports in common between athletes of all nations with a search for the individual excellence, but not yet of international competition or rewards.
The autograph draft of this Coubertin thesis, largely modified by the author in the preparation phase, was sold for $ 8.8M from a lower estimate of $ 700K by Sotheby's on December 18, 2019, lot 173.
Very remarkably, despite necessarily different visions of his international interlocutors, it is Coubertin himself who will concretize his concept. A January 1894 autograph document defining the stadium and sports passed at Goldin Auctions on October 29, 2016. In June 1894, Pierre de Coubertin creates the International Olympic Committee.
Pierre de Coubertin's Olympic Address (commonly known as The Olympic Manifesto or his 1892 speech/manifesto) was sold by Sotheby's in New York on December 18, 2019, as Lot 173 in the "Fine Books and Manuscripts, Including the Olympic Manifesto" auction. This 14-page autographed manuscript in French was Coubertin's original handwritten draft (with inscriptions and corrections) of his keynote address delivered on November 25, 1892, at the annual meeting of the Union des Sociétés Françaises de Sports Athlétiques (Union of French Athletic Sports Societies) in Paris at the Sorbonne. It marked his first public call for the revival of the ancient Olympic Games after nearly 1,500 years.Auction Details
The address passionately advocated for the re-establishment of the Olympic Games as a modern international festival of athletics, education, and moral/physical development. Coubertin argued that reviving the Games would promote physical education in schools (inspired by British models), foster international understanding among youth, and counterbalance the militarism and nationalism of his era through peaceful competition.
Key themes included:
"The important thing in life is not the triumph but the struggle; the essential thing is not to have conquered but to have fought well." (Original French: "L’important dans la vie ce n’est point le triomphe, mais le combat, l’essentiel ce n’est pas d’avoir vaincu mais de s’être bien battu.") This encapsulated his emphasis on participation, effort, and moral growth over mere victory.
The speech initially met with limited enthusiasm, but it laid the groundwork for the 1894 Sorbonne Congress, where the International Olympic Committee (IOC) was founded and the first modern Games set for Athens in 1896.
Intention and Biography of Coubertin
Pierre de Coubertin (full name: Charles Pierre de Frédy, Baron de Coubertin; born January 1, 1863, in Paris; died September 2, 1937, in Geneva) was a French aristocrat, educator, historian, and humanist. Influenced by the French defeat in the Franco-Prussian War (1870–1871), he sought ways to strengthen French youth through physical education. He admired British public schools' emphasis on sports and American collegiate athletics.
His primary intention was educational reform: to integrate sport into schooling to build character, discipline, and international goodwill. He viewed the revived Olympics not as mere competitions but as a "state of mind" (Olympism) promoting harmony, peace, and the balanced development of body and mind ("mens sana in corpore sano"). A pacifist and internationalist, he aimed to channel national rivalries into athletic rather than military arenas, creating a global festival every four years. He co-founded the IOC in 1894, served as its president (1896–1925), and shaped its rituals and ideals.
Global Legacy of the Olympic Games Project
Coubertin's vision transformed the Olympics into the world's largest peaceful international event, held every four years (with interruptions for wars), involving nearly every nation and billions of viewers. The modern Games emphasize:
This episode underscored the immense cultural and historical value of Coubertin's work, turning a once-overlooked speech into one of the most expensive documents ever sold.

1894 2nd Symphony by Mahler
2016 SOLD for £ 4.55M by Sotheby's
A child prodigy, Gustav Mahler becomes a conductor and uses his spare time for musical composition. His other passion is to Catholic mysticism despite he is a Jew. He is inspired by the symphonies of Liszt and Bruckner and by the grandiose construction of Wagner's operas.
Attending von Bülow's funeral in 1894, Mahler is dazzled by the ode to the Resurrection by Klopstock. He immediately begins his second symphony in five movements starting with the symphonic poem Todtenfeier which he had composed in 1888. The next phases form a dramatic crescendo leading to the exalted fortissimo of the fifth movement.
Mahler's second symphony is monumental by its duration close to an hour and a half and by its orchestra requiring 90 musicians accompanied by choirs and by soloists in soprano and alto. The conductor Semyon Bychkov comments : “At the end of it you feel that you have arrived in heaven having gone through hell”.
In 1965 the businessman Gilbert Kaplan is in his turn overwhelmed by the second symphony. He has conductor skills which he thereafter devotes exclusively to this piece.
Written from April to December 1894, the autograph manuscript of the second symphony in 232 pages 35 x 27 cm remains complete with its reworks, its withdrawals and its additions. It has never been bound.
Coming from the deceased estate of Kaplan who had acquired it in private sale in 1984, the manuscript was sold for £ 4.55M from a lower estimate of £ 3.5M by Sotheby's on November 29, 2016, lot 36. Please watch the video shared by the auction house.

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.

Albert Einstein : Influence on the advancement of Physics, Astronomy and overall on Science and Knowledge. Psychological evaluation.
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. Object relations theory highlights symbolic motivations in his creativity. However, these are interpretive, not diagnostic. Einstein remained mentally sharp until death, with no major psychiatric issues noted. Late talking, often called "Einstein Syndrome," can indicate either developmental delays or normal variation in bright individuals. Overall, his psychology reflects a unique blend of genius-level cognition and eccentricity, potentially enhanced by neurodivergent traits, though unconfirmed.

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. Object relations theory highlights symbolic motivations in his creativity. However, these are interpretive, not diagnostic. Einstein remained mentally sharp until death, with no major psychiatric issues noted. Late talking, often called "Einstein Syndrome," can indicate either developmental delays or normal variation in bright individuals. Overall, his psychology reflects a unique blend of genius-level cognition and eccentricity, potentially enhanced by neurodivergent traits, though unconfirmed.
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.
