Austrian-born Israeli logician, philosopher, and linguist.
Bar-Hillel obtained his doctorate from the Hebrew University, Jerusalem, in 1947. He worked for several years in the USA, first at Chicago, where he was much influenced by Carnap, and later at the Massachusetts Institute of Technology, where he became interested in the problem of developing an artificial language. After 1961, however, he was based in Jerusalem, where he was professor of logic and the philosophy of science at the Hebrew University.
As a pupil of Carnap, Bar-Hillel worked initially on problems in the fields of semantics and inductive logic. Later work was concerned with the possibility of machine translation and, under the influence of Chomsky, on the relationship between grammar, logic, and language. This later work is best seen in two collections of his essays, Language and Information (1964) and Aspects of Language (1970).
