This name was popularized in continental Europe by the works of the 18th-century Scottish poet James Macpherson [1]. Napoleon was an admirer of Macpherson, and he suggested Oscar as the second middle name of his godson, who eventually became king of Sweden as Oscar I. Other notable bearers include the Irish writer and humorist Oscar Wilde (1854-1900) and the Brazilian architect Oscar Niemeyer (1907-2012).

This name was fairly popular at the end of the 19th century and beginning of the 20th. The American author F. Scott Fitzgerald used it for the character of Daisy Buchanan in The Great Gatsby (1925).

It was at a low in popularity in the United States in the 1970s when it got a small boost from a character on the television series The Dukes of Hazzard in 1979.
