John Stepan Zamecnik (May 14, 1872 in Cleveland, Ohio – June 13, 1953 in Los Angeles, California) was an American composer and conductor.

(Jane) Hathaway, Kathryn Hawthorne, Roberta Hudson, Ioane Kawelo, J. Edgar Lowell, Jules Reynard, F. (Frederick) Van Norman, Hal Vinton and Grant Wellesley.

When the Hippodrome commenced with the screening of silent films, Zamecnik began to compose music scores for them.

Jackie Gleason's American Scene Magazine television series in the 1950s used this version to open a skit that parodied current events.

In 2011 Paramount Pictures secured the original manuscript score of the cues composed by Zamecnik for Wings from the Library of Congress.
