`Hoare's interest in computing was awakened in the early 1950s, when he studied philosophy (together with Latin and Greek) at the Univ. of Oxford, under the tutelage of John R. Lucas. He was fascinated by the power of mathematical logic as an explanation of the apparent certainty of mathematical truth.'
