BOHR, Niels Henrik David.
On the Quantum Theory of Line-Spectra, I-III [all published].

Copenhagen: Bianco Lunos, 1918-1922. All first editions. Nobel laureate Percy W. Bridgeman’s annotated copies. Besides Bohr’s derivation of the Balmer formula (1913) this work, in which he first gave a clear formulation of his ‘correspondence principle’, is by many considered to be his greatest contribution to physics.

ROSENBLATT, Frank.
The Perceptron: A Probabilistic Model for Information Storage and Organization in the Brain [with] The Design of an Intelligent Automaton [with] Two Theorems of Statistical Separability on the Perceptron.

Washington and Teddington: American Psychological Association, Office of Naval Resaerch, National Physical Laboratory, 1958. First edition, offprint issues. Three exceptional and rare offprints on the beginning of neural networks and artificial intelligence - the perceptron. “Rosenblatt’s paper (The Perceptron: A Probabilistic Model ...) introduced the perceptron, the first precisely specified, computationally oriented neural network (‘Neural network’ is the term used to describe a system deliberately constructed to employ...

WALD, Abraham. & H.A. Freeman.
Sequential Analysis of Statistical Data: Theory [with] Sequential Tests of Statistical Significance [with] Sequential Analysis of Statistical Data: Applications.

Washington: National Defense Research Committee, 1943-1944. All three first editions, first issue. An exceptional set of the three classified reports in which Wald's groundbreaking work was first announced. About Wald's later journal paper from 1945 Kotz and Johnson write in their 'Breakthroughs in Statistics': "Probability theory came of age with the advent of Kolmogorov's axiomatics in 1933 and the subsequent developments in...
