Leroy P. Steele Prize
The Leroy P. Steele Prizes are awarded every year since 1970 by the American Mathematical Society for distinguished research work and writing in the field of mathematics. Since 1993, the awards have been split into three categories: lifetime achievement, mathematical exposition, and research.
The prizes were begun from a bequest of Leroy P. Steele and were set up in honor of George David Birkhoff, William Fogg Osgood and William Caspar Graustein. The way the prizes are awarded was changed in 1976 and 1993, but the initial aim of honoring expository writing as well as research has been retained. The prizes—$10,000 for lifetime achievement, and $5,000 for mathematical exposition and for research—are not given on a strict national basis, but relate to writing in English (originally, or in translation) and mathematical activity in the United States.
