Emmett Grogan (c.1943--1978) was born Eugene Grogan in Brooklyn, New York. Called a Superman of the Underground by The Times (London), he was the founder of the Diggers, a legendary anarchistic group in the San Francisco Bay Area during the 1960s that supplied free food, housing, and medical aid to runaways. On April 6, 1978, the thirty-five-year-old Grogan was found dead on a subway car in New York City, possibly of a drug overdose. Besides his autobiography, Grogan was the author of Final Score, a fictional crime novel.
