Why Is Otomar Hájek Influential?

(Suggest an Edit or Addition)

According to Wikipedia, Otomar Hájek was a Czech-American mathematician, known for his contributions to dynamical systems, game theory and control theory. He was born in Belgrade in Serbia, moving with his family to Prague in 1935, to the Netherlands in 1939 and via Algerie and southern France to London in 1940 where they lived until 1945 when they returned to Prague. After high school in 1949 he studied mathematics at Charles University in Prague, resulting in a Ph.D. in 1963 on a thesis entitled Dynamical systems in the plane. At the same place he joined the mathematics and physics faculty in 1965, before moving in 1968 to Cleveland and Case Western Reserve University where he worked until 1995 as professor, becoming an emeritus in 1996.
