Everett C. Dade
Everett Clarence Dade is a mathematician at University of Illinois at Urbana–Champaign working on finite groups and representation theory, who introduced the Dade isometry and Dade's conjecture. While an undergraduate at Harvard University, he became a Putnam Fellow twice, in 1955 and 1957.

Work
The Dade isometry is an isometry from  class functions on a subgroup H with support on a subset K of H to class functions on a group G . It was introduced by  as a generalization and simplification of an isometry used by  in their proof of the odd order theorem, and was used by  in his revision of the character theory of the odd order theorem.

Dade's conjecture is a conjecture relating the numbers of characters of blocks of a finite group to the numbers of characters of blocks of local subgroups.
