Gregory Sierra Autographs
Gregory Joseph Sierra (January 25, 1937 – January 4, 2021) was an American actor known for his roles as Detective Sergeant Chano Amengual on Barney Miller; Julio Fuentes, the Puerto Rican neighbor of Fred G. Sanford on Sanford and Son, Marruja in The Castaway Cowboy (1974); and Lieutenant Lou Rodriguez in the first four episodes of Miami Vice.
Gregory Joseph Sierra was born on January 25, 1937, in Manhattan. He was raised in Spanish Harlem by an aunt because his parents did not take charge of his care. After serving in the Air Force, Sierra went with a friend to an acting school audition in Manhattan. Sierra was there only to support his friend, but after performing some improvisation, he was admitted instead of his friend.
He began his career on the stage, touring with the National Shakespeare Company, and in 1967, appeared as the Duke of Austria in King John at the New York Shakespeare Festival. He moved to Los Angeles in the late 1960s to work in film and television.
