Haruzo Hida, UCLA, will receive the 2019 Leroy P. Steele Prize for Seminal Contribution to Research for his highly original paper “Galois representations into GL2(Zp[[X]]) attached to ordinary cusp forms,” published in 1986 in Inventiones Mathematicae.

*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 $5,000.

*Special Note*: The Steele Prize for Seminal Contribution to Research is awarded according to the following six-year rotation of subject areas:

- Open
- Analysis/Probability
- Algebra/Number Theory
- Applied Mathematics
- Geometry/Topology
- Discrete Mathematics/Logic

Hida made the fundamental discovery that ordinary cusp forms occur in *p*-adic analytic families. Hida families are now ubiquitous in the arithmetic theory of automorphic forms, and his research has changed the way we view the subject.
