Ludwig Wittgenstein (1889-1951) was arguably the most influential philosopher of the twentieth century. He was born in Vienna, but studied and practiced philosophy in Great Britain. He was a professor of philosophy at the University of Cambridge from 1939 until 1947. He worked in and transformed the fields of logic, the philosophy of mathematics, the philosophy of mind, and the philosophy of language.
Anscombe (1919-2001) read classics and philosophy at St Hugh's College, Oxford from 1937 to 1941 in which year she married the philosopher Peter Geach. She subsequently researched in philosophy at Newnham College, Cambridge where she became a student and friend of Ludwig Wittgenstein. One of his literary executors, she played a large part in editing his unpublished works and was their principal English translator. In 1946 she returned to Oxford as a University Lecturer in 1951. From 1970 until her retirement in 1986 she held the Chair of Philosophy at Cambridge.
