Stefan Banach

Stefan Banach (1892-1945) was the greatest Polish mathematician and co-founder of the famous Polish School of Mathematics developed in the interwar period of 1918-1939. One of the major prizes of the Polish Mathematical Society (which he co-founded and chaired in the years 1939-1945) and the medal of the Polish Academy of Sciences awarded alternately to either a Polish or a foreign mathematician every year, are named after Stefan Banach. His name is associated with a number of mathematical concepts and theorems, in particular the concept of Banach spaces, the Hahn-Banach theorem and the Banach fixed-point theorem (to which the images on the collector coins are linked). These concepts and theorems are presently not only known to professional mathematicians, but also to students ...
