Neil Bohr's Signed Copy of Immanuel Kant's, Critik der Reinen Vernunft

Physics Nobel Prize winner Neil Bohr personal signed copy of  Immananuel Kant's, Critik der Reinen Vernunft. Riga, Johann Hartnoch, 1787, 2nd edition. The first printing of "Version B". Contemporary half calf, spine gilt, a tiny chip to the top of the spine. Signed "Bohr" in blue pencil on front fly leaf. Bookplate of The Garden, Ltd. 7.75" x 5". 

The most famous work of European philosophy, Kant's Critik studies how the thinking subject synthesizes experience to the achievement of cognition. Philosopher's call the present text of the Critik "Version B": the final state of the text, it is extensively rewritten form of the first edition ("Version A"); philosophers think it necessary to have both versions of the text at hand when studying the Critik. This is an especially interesting association copy, since the quantum physics of Neils Bohr profoundly challenged the validity of Kant's a priori categories.

Biography Niels Henrik David Bohr:

A Danish physicist who made foundational contributions to understanding atomic structure and quantum theory, for which he received the Nobel Prize in Physics in 1922. Bohr was also a philosopher and a promoter of scientific research. Bohr developed the Bohr model of the atom, in which he proposed that energy levels of electrons are discrete and that the electrons revolve in stable orbits around the atomic nucleus but can jump from one energy level (or orbit) to another. Although the Bohr model has been supplanted by other models, its underlying principles remain valid. He conceived the principle of complementarity: that items could be separately analyzed in terms of contradictory properties, like behaving as a wave or a stream of particles. The notion of complementarity dominated Bohr's thinking in both science and philosophy. Bohr founded the Institute of Theoretical Physics at the University of Copenhagen, now known as the Niels Bohr Institute, which opened in 1920. Bohr mentored and collaborated with physicists including Hans Kramers, Oskar Klein, George de Hevesy, and Werner Heisenberg. He predicted the existence of a new zirconium-like element, which was named hafnium, after the Latin name for Copenhagen, where it was discovered. Later, the element bohrium was named after him. During the 1930s Bohr helped refugees from Nazism. After Denmark was occupied by the Germans, he had a famous meeting with Heisenberg, who had become the head of the German nuclear weapon project. In September 1943 word reached Bohr that he was about to be arrested by the Germans, and he fled to Sweden. From there, he was flown to Britain, where he joined the British Tube Alloys nuclear weapons project, and was part of the British mission to the Manhattan Project.
