 Little is known about Lefèvre’s family and early training. He came from Étaples, on the coast of Picardy, and by the early 1490s he was teaching in the Collège du Cardinal Lemoine in Paris. In an unusually long teaching career of nearly two decades, he became the college’s most revered teacher, elevating it out of relative obscurity. His reputation as a philosopher was cultivated in the classroom and in countless editions of philosophical works; any account of his thought must first place this diverse body of work within the context of his life.
