This is the grave of Hugh Marlowe.
Born Hugh Hipple in Philadelphia in 1911, Marlowe moved to California as a young man. He got quite a bit of theater and stage work in the late 30s and into the 40s. His first film was Brilliant Marriage in 1936, which I have never seen. He became a major supporting actor of the period in such films as The Day The Earth Stood Still, Elmer Gantry, Birdman of Alcatraz, Seven Days in May, All About Eve, Night and the City, and a whole lot of other films. Personally, I find him a bit stiff but certainly he appealed to a lot of people given the number of quality films he was in. He did a bunch of TV as well, which is where most actors who got their start in the 30s and 40s ended up. Unfortunately, he never appeared on Love Boat. Whenever I look up actors of Marlowe’s generation, I check this fact and at least 50% of the time, they were on an episode or more of Love Boat.
Hugh Marlowe died in 1982. He is buried in Ferncliff Cemetery, Hartsdale, New York.
