The 1988 Nobel Prize in Physics, awarded to particle physicist Leon Lederman for his discovery of the muon neutrino, a particle 200 times the size of an electron. Lederman, along with colleagues Melvin Schwartz and Jack Steinberger, found the muon neutrino in 1962 while using a high energy particle accelerator. They discovered that in some cases a muon (rather than an electron) was produced, illuminating the existence of a new atomic particle. Lederman was also instrumental in the discovery of the bottom quark in 1977, and was the champion of the Superconducting Super Collider. His popular 1993 book ”The God Particle: If the Universe is The Answer, What is The Question” was released to critical acclaim. This Nobel Prize is made of 18kt gold, plated in 24k gold, as were all Nobel Prize medals awarded after 1980. Medal features the relief portrait of Alfred Nobel to front, with his name and the years of his birth and death. Verso features a relief of the Goddess Isis, whose veil is held up by a woman who represents the genius of science. Encircling the medal are the words ”Inventas vitam juvat excoluisse per artes”, translating to ”And they who bettered life on earth by their newly found mastery”. Lederman’s name and 1988 in Roman numerals are engraved on a plaque below the relief of the two women, with ”Reg. Acad. Scient. Suec.” also written, an abbreviation for The Royal Swedish Academy of Sciences. Etched upon the medal is the name of Erik Lindberg, designer of the Nobel medal. Housed in the original red leather case with Leon Lederman’s name gilt stamped. Medal weighs 173 grams or just over 6 oz. and measures 2.5” in diameter, consistent with the original Nobel Prize awarded in 1988. Case measures 5.5” x 5.5” x 1”. Presented in near fine condition, and with an LOA from Leon Lederman. Sold for $765,002.


Albert Einstein typed letter signed during World War II, with moving content regarding helping Jewish refugees. Dated 10 June 1939 on his personal embossed letterhead from Princeton, Einstein writes to Dr. Maurice Lenz who worked on ”behalf of the refugees during Dedication Week.” Einstein continues, ”…The power of resistance which has enabled the Jewish people to survive for thousands of years has been based to a large extent on traditions of mutual helpfulness. In these years of affliction our readiness to help one another is being put to an especially severe test. May we stand this test as well as did our fathers before us.
We have no other means of self-defense than our solidarity and our knowledge that the cause for which we are suffering is a momentous and sacred cause.
It must be a source of deep gratification to you to be making so important a contribution toward rescuing our persecuted fellow-Jews from their calamitous peril and leading them toward a better future…[signed] A. Einstein”.
Single page letter measures 8.5” x 11”. Folds and light creasing, otherwise near fine condition. Accompanied by Einstein’s embossed mailing envelope, postmarked Princeton on 12 June 1939. Sold for $134,344.

Very rare photo signed by Albert Einstein, on the occasion of the Nobel Prize winner playfully sticking out his tongue to a group of photographers on his 72nd birthday. Photo was snapped on 14 March 1951 by Arthur Sasse, a UPI photographer whose employers were at first hesitant about publishing the iconoclastic image of Einstein; when they did, Einstein was so amused by it that he ordered several prints to give out to close friends. This image is unlike most which crop the photo to show only Einstein. Here, the photo is shown in its full context with Einstein seated between Dr. Frank Aydelotte, head of the Institute of Advanced Study in Princeton, and Aydelotte’s wife, after celebrating his birthday at the Princeton Club. Photo is signed along the left margin ”A. Einstein .51”, indicating he signed the image shortly after it was taken. Photo measures 7” x 10”. Very good to near fine condition. Extraordinarily rare photo signed by Einstein, the most famous and beloved image of him. Sold for $125,000.

Nobel Prize Awarded to Physicist Kenneth G. Wilson in 1982 — One of the Kingpins of Quantum Physics
The 1982 Nobel Prize in Physics, awarded to theoretical physicist Kenneth G. Wilson for his work in understanding the ”critical point” of phase transitions – the exact point at which matter transitions to another state, such as when a solid become liquid. Wilson’s work was subsequently applied to quantum mechanics, where he is considered a pioneer who laid the theoretical groundwork for today’s quantum physicists. Nobel Prize is made of 18kt gold, plated in 24kt gold, consistent with the 1982 medals. Medal features the relief portrait of Alfred Nobel to front, with his name and the years of his birth and death. Verso features a relief of the Goddess Isis, whose veil is held up by a woman who represents the genius of science. Encircling the medal are the words ”Inventas vitam juvat excoluisse per artes”, translating to ”And they who bettered life on earth by their newly found mastery”. Wilson’s name and 1982 in Roman numerals are engraved on a plaque below the relief of the 2 women, with ”Reg. Acad. Scient. Suec.” also written, an abbreviation for The Royal Swedish Academy of Sciences. Etched upon the medal is the name of Erik Lindberg, designer of the Nobel medal. Housed in the original red leather case with Kenneth G. Wilson’s name gilt stamped. Medal weighs 173 grams or just over 6 oz. and measures 2.5” in diameter. Case measures 5.5” x 5.5” x 1”. Presented in near fine condition. With an LOA from Kenneth Wilson’s widow. Sold for $118,750.


Albert Einstein letter signed with his hand drawings, elegantly explaining his electrostatic theory of special relativity to a physics teacher struggling to reconcile it with experiments he was conducting. In addition to the letter, which is new to the market, Einstein generously replies to a series of questions the teacher asks him on a questionnaire, providing additional drawings and calculations, initialed ”A.E.” at the conclusion. Dated 4 September 1953 on Princeton’s Institute for Advanced Study letterhead, Einstein writes to Arthur L. Converse, the teacher from Malcolm, Iowa, in part, ”There is no difficulty to explain your present experiment on the basis of the usual electrostatic theory. One has only to assume that there is a difference of potential between the body of the earth and higher layers of the atmosphere, the earth being negative relatively to those higher layers…[Einstein then draws Earth and the atmosphere, referring to it for clarification] The electric potential p rises linearly with the distance h from the surface of the earth…For all your experiments the following question is relevant: How big is the electric charge produced on a conductor which is situated in a certain height h, this body being connected with the earth…” Einstein then answers Converse’s questions on a two-page questionnaire. In one answer, Einstein seems to disagree with the question, providing both a diagram and mathematical equation and then a ”?” to try to aid understanding. He later writes ”not clear” to one answer along with a question mark and additional diagram with the notation ”charge of elektroscope increased proportional to h”. An extraordinary lot by Einstein showing the generosity of his time, with rare content on his theory of special relativity. Single page letter and two-page questionnaire each measures 8.5” x 11”. Also included is Einstein’s original mailing envelope from ”Room 115” of the Institute for Advanced Study, postmarked 7 September 1953 from Princeton. Folds and very light toning to letter, otherwise near fine. Questionnaire has folds, light toning and staple mark, otherwise near fine with bold handwriting by Einstein. With an LOA from the nephew of Arthur Converse and new to the market. Sold for $53,504.

Stephen Hawking Signed Book From 1973 — One of the Scarcest of Signatures
Stephen Hawking book signed from 1973, shortly before Hawking was not able to write his name due to ALS. Hawking signed this book, ”The Archaeology of the Industrial Revolution”, along with several other members of the Institute of Theoretical Astronomy at Cambridge University, on the occasion of an employee leaving his job as a computer operator. Hawking signs the half-title page, ”Stephen Hawking”, in stilted, but legible writing, below the signatures of other faculty members and below the gift inscription, ”With gratitude and best wishes from the friends of the IOA computer staff.”
It was at the Institute of Theoretical Astronomy at Cambridge where Hawking, as a research scientist, made some of his earliest scientific breakthroughs regarding black holes and quantum mechanics. Also in 1973, he published his important first book, ”The Large Scale Structure of Space-Time” which is now considered a classic and has been printed many times over. It was also at this time that ALS was overtaking Hawkings physically, and he would be confined to a wheelchair by 1975.
First edition book, published in 1973, measures 9” x 11.25” with dust jacket. Light pulling away from binding at bottom of signature page, but overall in near fine condition. Accompanied by email chain of provenance originating from the recipient of the book. A fantastic item, captured during the brief time that Hawking’s physical condition was deteriorating but his intellectual achievements were rapidly accelerating. Sold for $25,000.

Stephen Hawking ownership signature within ”Astrophysical Quantities”, one of the most referenced books in the discipline of astrophysics. London: The Athlone Press, 1964 second edition by Clabon Allen. Signed by Hawking on the front free endpaper in black ballpoint, ”S.W. Hawking”, with the bookseller’s date in pencil reading ”4-6-70”, revealing when Hawking most likely purchased and signed the book. At this time in 1970, Hawking was doing his most vigorous work on black holes, and theorized what is now accepted as the second law of black hole dynamics. This book, ”Astrophysical Quantities” was probably used repeatedly by the legendary scientist at the time. Book measures 6.875” x 9.75”, bound in publisher’s forest green boards and housed in original dust jacket. Jacket has some sunning to spine and a few nicks, in very good condition. Book itself is near fine. With University Archives COA. Sold for $25,000.

The Enrico Fermi Award presented to Nobel Prize-winning physicist Leon Lederman in 1992. The Fermi Award, first given in 1956, honors scientists from around the world for their lifetime achievements, with many of the recipients also winning Nobel Prizes. Medal features a relief portrait of Enrico Fermi, with his name and the years of his birth and death. ”SCIENTIA PROGRESSUS” is also engraved on front, which translates from Latin to ”the progress of science”. Verso reads: ”PRESENTED TO / LEON LEDERMAN / FOR ESPECIALLY MERITORIOUS CONTRIBUTIONS TO THE DEVELOPMENT, USE, OR CONTROL OF ATOMIC ENERGY / 1992” and is framed by the words, ”DEPARTMENT OF ENERGY / UNITED STATES OF AMERICA”. Gold-plated medal weighs 324 grams or 11.4 ounces, and measures 3” in diameter. Case measures 5.25” x 5.25” x 1.5”. Very small mark on front of medal on Fermi’s lapel. Near fine condition. With an LOA by Leon Lederman. Sold for $25,000.
