Jane Rotrosen Berkey dropped out of college in 1974 to start a literary agency for smut writers. In 1985 she got bored of that and dropped some $2.5 million to buy the Animal Farm Foundation, a nonprofit that she and her brother keeps pumping money into. Where does her money come from? All inherited from her father, Joseph Saul, who was a kike on the board for "American Friends of the Israel Museum."
