Atomic Physics, Quantum Theory
Braunschweig: Vieweg & Berlin, 1922. First edition, the very rare offprints, of the famous Stern-Gerlach experiment, which demonstrated the spatial quantization predicted by the Bohr-Sommerfeld quantum theory of the atom and (although this was not realised until later) the existence of electron spin. “This direct demonstration of spatial quantization was...

Lancaster: American Physical Society, 1930. First edition, offprint issue, of this important paper which introduced the ‘Ornstein-Uhlenbeck process.’ Although its origins lay in statistical mechanics, this process has found a wide variety of applications, notably in mathematical finance. The Ornstein-Uhlenbeck process, also known as the ‘Langevin equation’ in the physics..... More

Berlin: Julius Springer, 1926-28. First editions, very rare offprint issues, of the papers that laid the foundations of the role of symmetry in quantum mechanics. “Wigner was a member of the race of giants that reformulated the laws of nature after the quantum mechanics revolution of 1924-25. In a series..... More
