V.A. Fock-The Destiny of Some Discoveries

A review of some papers by V.A. Fock published in 1926-1937 and playing an important role in modern physics is given. The papers both unjustly forgotten (the Fock-Fierz identities, quantization of magnetic flow, the Kaluza-Klein-Fock theory), and not quite correctly cited (Klein-Fock-Gordon equation, the Fock gauge) are discussed. Connection between the Fock 5th parameter method (the proper time method) and the modern theory of strings and membranes is elucidated.
