PFAS79 An original 6" x 4" hand signed photo for Austrian Bulgarian scientist Carl Djerassi who has personally signed the souvenir where his signature rests perfectly accompanying his portrait - has small top left corner place to allow otherwise great condition. On the reverse of the souvenir is an invitation to a book launch by Carl Djerassi about a mans sperm stolen by a woman scientist using a new technology of the time called ISCI making this surely the ultimate signed opportunity of Carl Djerassi of its kind. The signing is undedicated too.
Carl Djerassi was an Austrian-born Bulgarian-American pharmaceutical chemist, novelist, playwright and co-founder of Djerassi Resident Artists Program with Diane Wood Middlebrook. He is best known for his contribution to the development of oral contraceptive pills, nicknamed the "father of the pill"
