The year 2009 was the centenary of the birth, and the 25th anniversary of the death, of the outstanding Polish mathematician Stanisław Marcin Ulam. I will try to present you with a brief portrait of this extraordinary scientist. Stanisław Marcin Ulam was born on 13 April 1909 in Lwów (Lviv), and gained his education in that city. His father, Józef Ulam, was a lawyer, and his mother Anna (nee Auerbach) was the daughter of an industrialist. It was a wealthy, Polonized Jewish family which had arrived from Venice three generations earlier.
