Peter J. Freyd

Peter J. Freyd (born 5 February 1936, Evanston, Illinois)[1] is an American mathematician, a professor at the University of Pennsylvania, known for work in category theory and for founding the False Memory Syndrome Foundation.

Mathematical work[edit]

Freyd is perhaps best known as the author of the foundational book Abelian Categories: An Introduction to the Theory of Functors. This work culminates in a proof of Mitchell's embedding theorem.

In 2012 he became a fellow of the American Mathematical Society.[2]

False Memory Syndrome Foundation[edit]

Freyd and his wife Pamela founded the False Memory Syndrome Foundation in 1992,[3] after Freyd was accused of sexual abuse by his daughter Jennifer.[3][4] Freyd denies the accusations.[5]
