Richard L. Bishop

Richard Lawrence Bishop was an American mathematician who specialized in differential geometry and taught at the University of Illinois at Urbana–Champaign.
Bishop went to Case Institute of Technology as an undergraduate, earning a B.S. in 1954. Next he earned his Ph.D. from the Massachusetts Institute of Technology in 1959, and immediately joined the UIUC faculty, where he stayed until his retirement in 1997. His thesis, On Imbeddings and Holonomy, was supervised by Isadore Singer. At UIUC, his doctoral students included future UIUC colleague Stephanie B. Alexander. He is the author of Geometry of Manifolds and Tensor Analysis on Manifolds.
In 2013, Bishop became one of the inaugural fellows of the American Mathematical Society.
The Bishop–Gromov inequality in Riemannian geometry, one form of which appeared in his book with Crittenden, is named after him and Mikhail Gromov, who gave an improved formulation of Bishop's result. He introduced the "Bishop frame" of curves in Euclidean space, an alternative to the better-known Frenet frame.
