Winners of N. I. Lobachevskii international prize for mathematics (Q1901956)

This article gives a complete list and biographical information on all winners of the N. I. Lobachevskii International Prize for Mathematics. Sources of the biographical information are not specified. The prize was founded in 1895 by the Kazan Physics-Mathematics Society on the occasion of the centenary of the famous Russian mathematician and founder of non- Euclidean geometry, N. I. Lobachevskii (1792-1856). It has been awarded since 1897 primarily for geometric and topological work, approximately once in every four years with several interruptions mainly due to the World Wars. Many prize-winners before 1930 were foreigners (mostly Germans). Later on, however, especially after (in 1950) the central Soviet Academy claimed the right to award the prize, the majority of prize-winners were citizens of the Soviet Union. The prize-winners include S. Lie (1897), W. K. Killing (1900), D. Hilbert (1904), F. Schur and L. Schlesinger (both 1912), H. Weyl (1927), E. Cartan and V. V. Vagner (both 1937), N. V. Yefimov and A. D. Aleksandrov (both 1951), A. V. Pogorelov (1959), L. S. Pontryagin (1966), H. Hopf (1969), P. S. Aleksandrov (1972), B. N. Delone (1977), S. P. Novikov (year missing), H. Busemann (1984), A. N. Kolmogorov (1986), and F. Hirzebruch (1989). The prize seems since to have been changed into a ``Lobachevskii medal for outstanding achievements in the field of geometry'', which is to be awarded starting from 1992 by the Academic Council of Kazan University once in five years (p. 7.
