Leroy P. Steele Prizes
Each year, The Steele Prize is awarded in the following categories.

The Steele Prize for Lifetime Achievement is awarded for the cumulative influence of the total mathematical work of the recipient, high level of research over a period of time, particular influence on the development of a field, and influence on mathematics through Ph.D. students. The amount of this prize is US$10,000.

The Steele Prize for Mathematical Exposition is awarded for a book or substantial survey or expository research paper. The amount of this prize is US$5,000.

The Steele Prize for Seminal Contribution to Research is awarded for a paper, whether recent or not, that has proved to be of fundamental or lasting importance in its field, or a model of important research. The amount of this prize is US$5,000.
Special Note: The Steele Prize for Seminal Contribution to Research is awarded according to the following sixyear rotation of subject areas:
1. Analysis/Probability (2020);
2. Algebra/Number Theory (2021);
3. Applied Mathematics (2022);
4. Geometry/Topology (2017);
5. Discrete Mathematics/Logic (2018);
6. Open (2019).

Most Recent Prizes
Lifetime Achievement: January 2017
The 2017 Lifetime Achievement Prize was awarded to James Arthur for his fundamental contributions to number theory and harmonic analysis, and in particular for his proof of the ArthurSelberg trace formula.
Mathematical Exposition: January 2017
The 2017 Mathematical Exposition Prize was awarded to Dusa McDuff and Dietmar Salamon for their book Jholomorphic Curves and Symplectic Topology. It not only develops the topic from the basics, explaining essential notions and results in detail, but also describes many of the most spectacular results in this area.
Seminal Contribution to Research: January 2017
The 2017 Seminal Contribution to Research Prize was awarded to Leon Simon for his fundamental contributions to Geometric Analysis and in particular for his 1983 paper 'Asymptotics for a Class of NonLinear Evolution Equations, with Applications to Geometric Problems', published in the Annals of Mathematics.

More About this Prize
These prizes were established in 1970 in honor of George David Birkhoff, William Fogg Osgood, and William Caspar Graustein, and are endowed under the terms of a bequest from Leroy P. Steele. From 1970 to 1976 one or more prizes were awarded each year for outstanding published mathematical research; most favorable consideration was given to papers distinguished for their exposition and covering broad areas of mathematics. In 1977 the Council of the AMS modified the terms under which the prizes are awarded. In 1993, the Council formalized the three categories of the prize by naming each of them: (1) The Leroy P. Steele Prize for Lifetime Achievement; (2) The Leroy P. Steele Prize for Mathematical Exposition; and (3) The Leroy P. Steele Prize for Seminal Contribution to Research.
