Stanisław Szukalski (13 December 1893 – 19 May 1987) was a Polish (self-taught) sculptor and painter who became a part of the Chicago Renaissance. In 1930s Poland he enjoyed fame as a nationalist sculptor. He also developed the pseudoscientific–historical theory of Zermatism, positing that all human culture was derived from post-deluge Easter Island and that humankind was locked in an eternal struggle with the Sons of Yeti (“Yetinsyny”), the offspring of Yeti and humans.
Struggle: The Life and Lost Art of Szukalski is a 2018 documentary film directed by Irek Dobrowolski, written by Stephen Cooper and Irek Dobrowolski and starring Stanislav Szukalski, Glenn Bray and Robert Williams. (wiki)
