Lana Turner wasn't always named Lana Turner. She was born Julia Jean Mildred Frances Turner. Good thing she dropped the "Mildred" (source).
Frank O'Hara's college roommate was Edward Gorey, the writer and illustrator of incredibly creepy children's books. You should check out his book The Gashlycrumb Tinies, if you haven't already (source).
Frank O'Hara died in 1966 at the age of 40. He was killed in a tragic accident: hit by a dune buggy while vacationing on Fire Island (source).
