Directory:Logic Museum/Philotheus Boehner
Boehner was born Heinrich Boehner on February 17, 1901, in Lichtenau, Westphalia. He entered the Franciscan Order in 1920, and was given the name Philotheus, the Latin form of the Greek Philotheos, ("friend of God"). In 1927 he was ordained as a priest, although he was so ill with tuberculosis he was not expected to live. While he was resting he began his work as a medieval scholar by translating Etienne Gilson's work on Saint Bonaventura. He became a close friend of Gilson in the 1930s.
In the summer of 1940 Boehner moved to Saint Bonaventure College (now a university) where he lectured on Franciscan philosophy, and it was here that he began to build the Franciscan Institute into a centre of international Franciscan scholarship.
