(Suggest an Edit or Addition)

According to Wikipedia, Czesław Olech was a Polish mathematician. He was a representative of the Kraków school of mathematics, especially the differential equations school of Tadeusz Ważewski. Education and career In 1954 he completed his mathematical studies at the Jagiellonian University in Kraków, obtained his doctorate at the Institute of Mathematical Sciences in 1958, habilitation in 1962, the title of associate professor in 1966, and the title of professor in 1973.1970–1986: director of The Institute of Mathematics, Polish Academy of Sciences.1972–1991: director of Stefan Banach International Mathematical Center in Warsaw.1979–1986: member of the Executive Committee, International Mathematical Union.1982–1983: president of the Organizing Committee, International Congress of Mathematicians in Warsaw,1987–1989: president of the Board of Mathematics, Polish Academy of Sciences.1990–2002: president of the Scientific Council, Institute of Mathematics of the Polish Academy of Sciences.Czeslaw Olech, often as a visiting professor, was invited by the world's leading mathematical centers in the United States, USSR , Canada and many European countries. He cooperated with Solomon Lefschetz, Sergey Nikolsky, Philip Hartman and Roberto Conti, the most distinguished mathematicians involved in the theory of differential equations. Lefschetz highly valued Ważewski's school, and especially the retract method, which Olech applied by developing, among other things, control theory. He supervised nine doctoral dissertations, and reviewed a number of theses and dissertations.
