George M. Zaslavsky (Cyrillic: Георгий Моисеевич Заславский) (31 May 1935 – 25 November 2008) was a Soviet mathematical physicist and one of the founders of the physics of dynamical chaos.
Zaslavsky was born in Odessa, Ukraine on 31 May 1935. His father was an artillery officer who dragged his cannon in World War II and survived there. Zaslavsky received his education at the University of Odessa and moved to Novosibirsk in 1957 where a golden age of Siberian physics was beginning.
In 1965, Zaslavsky joined the Institute of Nuclear Physics where he became interested in nonlinear problems of accelerator and plasma physics. Roald Sagdeev and Boris Chirikov helped him form an interest in the theory of dynamical chaos. In 1968, Zaslavsky and his colleagues introduced a separatrix map that became one of the major tools in the theoretical study of Hamiltonian chaos.
