Harry Reser (born January 17, 1896, Piqua, Ohio, Ohio – died September 27, 1965, New York City, New York, USA) was an American banjo player and bandleader. He became most known for leading the Clicquot Club Eskimos, one of radio’s first long-running shows (1923-1933, 1935-1936). His Six Jumping Jacks records are cited as precursors to the style later popularized by Spike Jones.
