Pauli letter collection: letter to Wolfgang Pauli

Bohr agrees with almost everything in Pauli's last letter. He reports on a long discussion of Heisenberg's theory and its relation to the earlier quantum theory and on the missing aspects and the future of Heisenberg's theory. His letter has given rise to many changes in Bohr's paper of which he encloses a proof published in: Nature : 116 (1945), 845 and in: Naturwissenschaften : 14 (1926), pp.1.
