Matematycy polscy i polskiego pochodzenia w Europie Zachodniej i obu Amerykach : ludzie i losy

Dramatic history of Poland in the years 1772-1989 and internal hardships have caused an immense brain drain in two main directions, East and West. The article is concentrated upon the latter one and lists some 50 Polish mathematicians who went to the West before 1946. Tere are also mentioned several people who were born in Poland and lived in the West but didn't feel particularly attached to their native country. In the period of communist rule (1946-1989) the number of mathematician-emigrants from Poland (all to the West) has surpassed 300 and so here only some statistical data are provided and only a few names are explicitly mentioned.
