Yehoshua Bar-Hillel

In 1933 he emigrated to Palestine with the Bnei Akiva youth movement, and briefly joined the kibbutz Tirat Zvi before settling in Jerusalem and marrying Shulamith.Bar-Hillel received his PhD in Philosophy from the Hebrew University where he also studied mathematics under Abraham Fraenkel, with whom he eventually coauthored Foundations of Set Theory (1958, 1973).Bar-Hillel was a major disciple of Rudolf Carnap, whose Logical Syntax of Language much influenced him.Later he expressed doubts that general-purpose fully automatic high-quality machine translation would ever be feasible.His teachings and writings strongly influenced an entire generation of Israeli philosophers and linguists, including Asa Kasher and Avishai Margalit.
