Henryk Hiż
Henryk Hiż (8 October 1917 – 19 December 2006) was a Polish analytical philosopher specializing in linguistics, philosophy of language, logic, mathematics and ethics, active for most of his life in the United States, one of the youngest representatives of the Lwów–Warsaw school.

A disciple of Tadeusz Kotarbiński, Hiż studied at the University of Warsaw. During the German occupation of Poland in the World War II, he participated in the Polish resistance movement as a cryptographer in the Home Army. In 1944 he took part in the Warsaw Uprising. In 1948, he defended his Ph.D. at Harvard University under W.V.O. Quine.

In 1950, he permanently emigrated to the United States. He kept in touch with the American logical environment, including with Alfred Tarski, and maintained lively contact with the Polish academic community. He lectured at the University of Pennsylvania between 1960–1988. In 1976 he was a Guggenheim Fellow and a visiting fellow at the University of Cambridge. In 1982 he received the Alfred Jurzykowski Foundation Award. He was a member of the Warsaw Scientific Society.

He published about one hundred original papers in peer-reviewed scientific journals. Strongly influenced by the Lwów–Warsaw school, initially in his research he was interested in semantics, formal logic and methodology of the sciences. From the late 1950s, he dealt mainly with linguistics in relation to logic and philosophy. He described himself as a naturalist and linguistic behaviorist, assuming that the linguistic work is primarily about linguistic behavior. He called himself a “negative utilitarian”; and was also a pacifist and an atheist.
