I met him once when I was a drunken art student and he came to an opening of an important group show of realists that he was in at the Pennsylvania Academy of the Fine Arts. I was in the men’s room, and looked over as I was urinating and there he was standing next to me. I yelled his name, stuck out my hand, and he shook it. He was the nicest famous artist I have ever met.
In 1977 when Gregory was only 40 years old, he had a retrospective at the Hirshhorn Museum in Washington DC. In 2000, age 63, he hung himself.
