Robert Grosseteste (/ˈɡroʊstɛst/ GROHS-test; Latin:Robertus Grosseteste; c.1175 – 9 October 1253) was an English statesman, scholastic philosopher, theologian, scientist and Bishop of Lincoln. He was born of humble parents at Stradbroke in Suffolk. Upon his death, he was almost universally revered as a saint in England, but attempts to procure a formal canonization failed. A. C. Crombie calls him "the real founder of the tradition of scientific thought in medieval Oxford, and in some ways, of the modern English intellectual tradition".
