Stanisław Feliksiak (6 April 1906 – 30 June 1992) was a Polish zoologist and a director of the National Zoological Museum in Warsaw.
After graduating from the University of Warsaw in 1930 he spent some time in Canada studying the aquatic fauna of Nova Scotia and Newfoundland.
During the war, he gave lectures in the underground "Flying University" and participated in the Warsaw Uprising in Czerniaków.
After the war he was involved with Stanisław Lorentz and the Committee for the Evacuation of Cultural Property of Warsaw, helping recover specimens and material stolen from the Museum and taken to Germany by the Nazis.
[2] He edited the journal Memorabilia Zoologica (1958-1977) and contributed to biology textbooks, many of which, under Stalinist pressure did not include Mendelian genetics and instead promoted a view forwarded by Michurin and Lysenko.
