Franciszek Leja (b. January 27, 1885 in
Grodzisko Górne nearPrzeworsk - October 11, 1979 inKraków ,Poland ) was a Polish mathematician.He was born to a poor peasant family in the south-estern Poland. After graduating from the Univestity of Lwów he was a teacher of mathematics and physics in high schools from 1910 until 1923, among others in Kraków. From 1924 until 1926 he was a professor at the
Warsaw University of Technology and from 1936 until 1960 in theJagiellonian University .During the
Second World War he lectured on the underground universities inŁańcut andLezajsk . But after the German invasion of Poland in 1939 life there became extremely difficult. There was a strategy by the Germans to wipe out the intellectual life of Poland. To achieve this Germans sent many academics to concentration camps and murdered others. In one of such actions he was sent to theSachsenhausen concentration camp which he fortunately survieved.Since 1948 he worked for the Institute of Mathematics of the
Polish Academy of Sciences . He was a co-founder of the Polish Mathematics Society in 1919 and from 1963 until 1965 the chairman. Since 1931 he was a member of the Warsaw Science Society (TNW).His main scientific interests concentrated on
Analytic functions , in particular the method of extremal points and transfinite diameters.Works
