1510 The Codex Leicester of Leonardo da Vinci
1994 SOLD for $ 31M including premium by Christie's
narrated in 2020
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 twice by Christie's, for $ 5.1M on December 12, 1980 and for $ 31M including premium 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.

1687 The Universal Philosophy revealed to the World
2016 SOLD for $ 3.7M including premium
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 sparingly.
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 in New York, Christie's sells a copy in a luxury binding in inlaid morocco, presented in that state by Smith to an unidentified recipient. It is estimated $ 1M, lot 167.
Another association copy with a binding of a comparable luxury is known. It was offered to King James II, patron of the Royal Society. This book was sold for $ 2.5M including premium by Christie's on December 6, 2013 over a lower estimate of $ 400K.

1802-1816 Les Liliacées by Redouté
1985 SOLD for $ 5.5M including premiumby Sotheby's
narrated in 2020
Specializing in botanical watercolors, the Belgian artist Pierre-Joseph Redouté comes to Versailles in 1788 for his career after training in the Royal gardens of Kew. From 1800 he contributes by his drawings to the reissue of the Traité des Arbres et Arbustes by Duhamel du Monceau and from 1798 he is the favorite artist of the future empress Joséphine.
His direct commitment to botany takes place in two phases : 486 watercolors on vellum on Liliaceae from 1802 to 1816 followed by 168 Roses from 1817 to 1824. His scientifically accurate drawings are taken from life in the gardens of La Malmaison, Saint-Cloud, Versailles and Sèvres.
All the watercolors of the Liliacées, bound in 16 volumes 48 x 35 cm for a total weight of nearly 150 kg, were originally entrusted to Joséphine's library in La Malmaison.
The lot was sold on November 20, 1985 for $ 5.5M including premium by Sotheby's after a sensational opening bid of $ 5M, the highest at that time in an art sale.
The buyer was a young dealer of rare books and prints named W. Graham Arader, who immediately made him known. To carry out this operation, he had created a syndicate of clients. Each share gave the right to own four watercolors, some were still available and he kept 30% of the whole. He had been the only bidder but according to his statements gathered by the New York Times he was covered up to $ 20M.
The pieces were chosen in turn by Arader's clients according to a priority determined by a draw. Arader has not disclosed the names of his shareholders. Steve Jobs was probably one of them.
The watercolor of an iris was sold for $ 200K including premium by Freeman's on April 29, 2018.

1827-1838 Audubon by Subscription
2010 SOLD 7.3 M£ including premium
Two books, or better two events, from a single collection are waiting for bibliophiles in the sale at Sotheby's in London on December 7: the First Folio of Shakespeare and Audubon's Birds of America.
Let's start with the birds. We already know them in the Prints group. Here is (slightly modified) how I summarized the importance of this work:
Lovers of top auctions remember the outstanding results obtained by Christie's in New York on the major work of Audubon, The Birds of America. The four volumes contain 435 hand colored etchings.
These prints are in double elephant folio size, the largest known format for an illustrated book: 100 x 67 cm. The gigantic size is related to the goal that John James Audubon managed for the great work of his life: he wanted all his birds being displayed in their natural habitat in life size, even for the largest. This American had to travel to England to find a publisher: he was Robert Havell, in London. The publication spanned twelve years (1827-1838). Such a duration was not unusual at this time for ambitious books.
The highest price achieved at Christie's, $ 8.8 million including premium, was recorded on March 10, 2000 on a copy constituted by subscription, whose colors remained remarkably fresh.
The copy for sale by Sotheby's, estimated £ 4M, has similar qualities. It was collected by the eleventh subscriber in Audubon's ledger, a paleobotanist from Edinburgh who was convinced of the value of the project during a wine party with the author.

1827-1838 The Grocer of Louisville
2019 SOLD for $ 6.6M including premium
In 1807 two young Frenchmen open a general store in Louisville, Kentucky. Jean-Jacques Audubon cannot concentrate on his work. He is passionate about hunting and bird watching. He takes the US citizenship in 1812 and anglicizes his first name as John James.
He is early trained in taxidermy and participates in one of the earliest attempts of bird ringing. His method is unprecedented. He kills his specimen with a shotgun and straightens it in a natural pose with a wire. Then he draws it life size, often with its female or its prey. He never draws from a stuffed bird.
Audubon goes bankrupt in 1819. Against the advice of his friends but with the support of his wife, he decides to publish his work. American learned societies repel this man from the woods who had ridiculed one of their honorable fellows. In 1826, right in the romantic period, he arrives in England with his collection of watercolors.
The work to be done is colossal. He wants to maintain the 97 x 66 cm format of his drawing sheets but no book has ever been printed in such a big size. The plates should be colored one by one by hand. The only solution is the subscription. He finds in Edinburgh in 1827 a printer, Lizars, to carry out the work. A first booklet of 10 plates, numbered from I to X, is prepared.
There will be no second issue by Lizars, following a strike of the colorists. The business is now entrusted to Havell in London, until the 435th and final plate in 1838. The five volumes of texts are published separately in octavo format between 1831 and 1839.
On December 18 in New York, Sotheby's sells a complete set, in very good condition despite the obscuring of some captions by the binding. It was formed for the subscription of the Yorkshire Philosophical Society received by Audubon in April 1827. Plates I, III, and V to X are in the first state printed by Lizars.
This lot was sold for £ 1.76M including premium by Sotheby's on June 21, 1990. It is now estimated $ 6M, lot 1. Please watch the video shared by the auction house.
The complete copy assembled around 1838 for the Duke of Portland with some remaining stock includes all the first ten plates in the Lizars edition and is in perfect condition. It was sold for $ 9.7M including premium by Christie's on June 14, 2018. A full set in its original binding, resulting from one of the very first subscriptions, was sold for £ 7.3M including premium by Sotheby's on December 7, 2010.

1838 The Birds of the Dukes of Portland
2018 SOLD for $ 9.7M including premium
The copy of The Birds of America by Audubon owned until 2012 by the Dukes of Portland is one of the finest in existence. It was sold for $ 8M including premium by Christie's in New York on January 20, 2012, lot 1.
It is now estimated $ 8M for sale in the same auction room on June 14 as lot 1, as a charity to benefit the conservation of the natural environment.
I narrated it as follows in 2012 :
The complete version of Audubon's The Birds of America, published in London, includes 435 plates engraved from 1827 to 1838, hand-colored from the watercolors of the author and bound in four volumes. Made in a quite large 'double elephant' folio format 98 x 65 cm, it is the masterpiece of illustrated books. All birds were carefully illustrated in life size.
The introduction at auction of a full version in good condition is an event. Two of these prestigious copies came from original deliveries by subscription. They were respectively sold for $ 8.8 million including premium at Christie's on March 10, 2000 and for £ 7.3 million including premium by Sotheby's on December 7, 2010.
At the end of the operation, Audubon's list included 161 subscribers. Its printers, Lizars and Havell, had planned it slightly wider, and it is likely that a few remaining copies have been assembled in volumes in 1838 for new customers while retaining the chronological order of publication.
The copy from the library of the Dukes of Portland is probably one of those assembled without subscription, and it remained in exceptionally fine condition. It may be considered like an original edition by the bibliophiles as most of the first plates are in first state, as evidenced by watermarks and through the variants in the legends. The five octavo volumes of texts are included in the lot.

1953 The Release of the Secret of Life
2013 SOLD 6.05 M$ including premium
The day after the announcement of the sale of Francis Crick's Nobel medal by Heritage, discussed yesterday in this column, Christie's issued a press release about an extraordinary document of the same origin, to be sold by them in New York on April 10.
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), 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. The estimate is quite open: $ 1M to 2M.
POST SALE COMMENT
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.
This manuscript is recognized as one of the greatest releases in the history of science: $ 6.05 million including premium.
Here is the link to the catalogue.

1962 The Invention of the Molecular Biology
2014 SOLD for $ 4.8M including premium
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.
The letter written by Crick to his young son showed that he was aware of the importance of the discovery. It was sold for $ 6,05M including premium by Christie's on April 10, 2013.
The Nobel Prize in Physiology or Medicine was awarded to Crick, Watson and Wilkins in 1962. Crick's Nobel medal and diploma were sold as a single lot for $ 2,27M including premium by Heritage on April 11, 2013.
Watson, now 86 years old, entrusted Christie's to sell his Nobel memories, offered in three lots on December 4 in New York. The Nobel medal with its case is estimated $ 2.5M, lot 1. His handwritten notes for the acceptance speech are estimated $ 300K,lot 2.
The manuscript of his Nobel lecture on the role of RNA in protein synthesis is estimated $ 200K, lot 3. Less than ten years after the discovery of the double helix, this theme highlighted the fact that the physicochemical mechanisms of life were already fully explained.
A portion of the proceeds from the sales will be donated by Dr. Watson to the benefit of scientific research and charities.

1987 The King of Badlands
2020 SOLD for $ 32M including premium
The successive discoveries of tyrannosaur fossil skeletons allow us to better understand the characteristics of this beast which lived at the end of the Cretaceous just before the final disaster of that era 66 million years ago. Stan is one of the specimens which provided the most elements to these analyzes.
We have to face the facts : the tyrannosaurus, a distant successor to the allosaurus, had characteristics much more efficient than humans, in terms of sight and smell, running speed, strength and appetite. I have no reliable data about its intelligence.
The deposits are mainly concentrated on the Hell Creek Formation, an island continent bordering Montana, the Dakotas and Wyoming. The distribution of the species was certainly wider, but the swamps of these Badlands originally limited the dispersal of the skeletons and provided good conditions for fossilization. More than 50 specimens have been found.
Hell Creek has been known since the beginning of the 20th century as a reservoir of tyrannosaurs. It was an amateur prospector who discovered in 1987 the hip bones of a specimen that was given his own first name, Stan. An error in paleontological interpretation delayed the researches. The excavation required 30,000 hours of work between 1992 and 1995. This male tyrannosaurus, approximately 70% complete in mass, is one of the largest specimens, measuring 11.3 m between the muzzle and the tip of the tail.
Traces on the bones provide valuable informations on the life of prehistoric animals. Stan had lesions created by the teeth of other tyrannosaurs. His broken neck had been healed by fusion of two injured vertebrae. He ate an edmontosaurus and a triceratops just before his death. In our time he plays the stars with more than 60 complete casts for use in museums and exhibitions.
The fossil includes 188 original pieces, compared with the 350 bones of a complete animal. The skull is almost perfect. Missing elements are represented by casts. It will be sold without a reserve price by Christie's in New York on October 6, lot 59 estimated $ 6M. Please watch the video shared by the auction house.
Stan deserves a similar notoriety as Sue, the 12.3 m long male tyrannosaurus found by a lady named Sue in 1990, which was sold for $ 8.4M including premium by Sotheby's on October 4, 1997.
We have to face the facts : the tyrannosaurus, a distant successor to the allosaurus, had characteristics much more efficient than humans, in terms of sight and smell, running speed, strength and appetite. I have no reliable data about its intelligence.
The deposits are mainly concentrated on the Hell Creek Formation, an island continent bordering Montana, the Dakotas and Wyoming. The distribution of the species was certainly wider, but the swamps of these Badlands originally limited the dispersal of the skeletons and provided good conditions for fossilization. More than 50 specimens have been found.

1990 Sue the Tyrannosaurus
1997 SOLD for $ 8.4M including premium by Sotheby's
narrated in 2020
On August 12, 1990 a team of paleontologists completed an excavation campaign in the Cheyenne River Indian Reservation in South Dakota. Upon leaving, they notice that a tire of the truck is flat. Sue Hendrickson takes advantage of this downtime to go to a cliff unexplored by the group. She finds the fossil remains of a tyrannosaurus rex that will be identified by her first name, Sue.
The bones had not been scattered. The animal had lived about 67 million years ago and probably died in a stream of water that pushed it against some obstacle.
The tyrannosaurus is the most spectacular of the dinosaurs, and Sue was the largest and most complete specimen at the time of its excavation. The skeleton is 90% complete by mass and 73% by the number of elements. The cranial fossil weighs 270 kg and is 1.40 m long and the teeth are almost intact.
The owner of the land, a member of the Sioux tribe, claimed that the team had paid him the right to take and clean up the fossil, but not the transfer of ownership. Justice follows and he becomes the sole owner of Sue. He then commissioned Sotheby's to manage the auction. Due to Sue's exceptional scientific interest, paleontologists were worried about the risk of purchase for a private collection.
Nothing equivalent had happened on the market. On October 4, 1997 the bidding was started at $ 500K. Sue was sold for $ 8.4M including premium to the Field Museum of Natural History in Chicago.
At the time of the sale, this dinosaur had been identified as exceptional but had never been mounted. Its exhibition at the Field Museum was inaugurated in May 2000. Scientific investigations have not been interrupted. The age of the animal is estimated at 28 years, making it until 2013 the dean of the tyrannosaurs. It was 12.30 m long and 4 m high at the hips and its weight in life was estimated at about 10 tons.
