Herman Raucher

Herman Raucher (born April 13, 1928) is an American author and screenwriter. He is best known for writing the autobiographical screenplay and novel Summer of '42, which became one of the highest-grossing films and one of the best selling novels of the 1970s, respectively. He began his writing career during the Golden Age of Television, when he moonlighted as a scriptwriter while working for a Madison Avenue advertising agency.

He effectively retired from writing in the 1980s after a number of projects failed to come to fruition, though his books remain in print and a remake of one of his films, Sweet November, was produced in 2001. From Wikipedia.
