In 1935 Vladimir A. Rokhlin entered the Moscow State University. His
teachers were A.I.Plesner, L.S.Pontriagin, P.S.Alexandrov, A.N.Kolmogorov,
I.M.Gel'fand.
Rokhlin was a volunteer in the beginning of the war in 1941. He was
a war prisoner in a German concentration camp and after the war he spent
two years in a Soviet filtration camp.
During 1947  1949 he made fundamental contributions to measure theory
and ergodic theory. He returned to these subjects after 1958 and made important
works in the theory of entropy.
In the 50s he obtained his famous results in topology (homotopy
groups of spheres, cobordisms of low dimensional manifolds, signature of
4manifolds, characteristic classes).
For the last 25 years of his life Rokhlin was a professor of the
Leningrad State University, where he created wellknown mathematical schools.
In this period his main interest was in characteristic classes, low dimensional
topology, and real algebraic geometry.
