Robert Grosseteste was a 13th-century English theologian, philosopher, and scientist who served as the Bishop of Lincoln. Born in Stradbroke around 1175, he became a prominent scholar at the University of Oxford, where he taught the Franciscans. His intellectual work spanned mathematics, physics, and astronomy, earning him recognition as a foundational figure for the scientific tradition in medieval Oxford. As a church leader, he was known for his reformist zeal and his commitment to the authority of the papacy, often clashing with secular rulers and local ecclesiastical authorities to uphold church prerogatives.
