Barry Mitchell (1933-2021) was an American mathematician who wrote one of the earliest books on category theory (1965). He proved what is sometimes called the Mitchell embedding theorem also called the Freyd-Mitchell embedding theorem, which shows that any abelian category has an exact embedding into a module category.
