 Richard Kilvington (ca. 1302–1361), Master of Arts and Doctor of Theology at Oxford, member of the household of Richard de Bury, then Archdeacon of London, and finally Dean of Saint Paul’s Cathedral in London. Along with Thomas Bradwardine, he represented the first academic generation of the school of Oxford Calculators. Although he brought new ideas and methods into logic, natural philosophy, and theology, and influenced his contemporaries and followers, he has been little studied until recently.
