Fritz Feld (October 15, 1900 – November 18, 1993) was a German-American film character actor who appeared in over 140 films in 72 years, both silent and sound. His trademark was to slap his mouth with the palm of his hand to create a "pop" sound.
Born Fritz Feilchenfeld in Berlin, Germany, Feld began his acting career in Germany in 1917, making his screen debut in Der Golem und die Tänzerin (The Golem and the Dancing Girl). Feld filmed the sound sequences of the Cecil B. DeMille film The Godless Girl (1929), released by Pathé, without DeMille's supervision since DeMille had already broken his contract with Pathé, and signed with Metro-Goldwyn-Mayer.
He developed a characterization that came to define him. His trademark was to slap his mouth with the palm of his hand to create a "pop!" sound that indicated both his superiority and his annoyance. The first use of the "pop" sound was in If You Knew Susie (1948).
