nLab Barry Mitchell

Barry Mitchell (1933-2021) was an American mathematician who wrote one of the earliest books on category theory (1965).

He proved what is now known as the Freyd-Mitchell embedding theorem, which shows that any abelian category has an exact embedding into a category of modules.
