Mae Clarke (born Violet Mary Klotz; August 16, 1910 – April 29, 1992) was an American actress. She is widely remembered for playing Henry Frankenstein's bride Elizabeth, who is chased by Boris Karloff in Frankenstein, and for being on the receiving end of James Cagney's halved grapefruit in The Public Enemy. Both films were released in 1931.
The Public Enemy, released that same year, contained one of cinema's most famous (and frequently parodied) scenes, in which James Cagney pushes a half grapefruit into Clarke's face, then goes out to pick up Jean Harlow. The film was so popular that it ran 24 hours a day at a theater in Times Square upon its initial release; Clarke's ex-husband had the grapefruit scene timed and would frequently buy a ticket, enter the theater to again enjoy that sequence, then immediately leave the theater.
Clarke appeared as Myra Deauville in the 1931 pre-Code version of Waterloo Bridge. In the film she portrays a young American woman who is forced by circumstance into a life of prostitution in World War I London; both the film and Clarke's performance were well received by the critics.
