Michael Patrick Dumble-Smith (born January 19, 1942), better known as Michael Crawford, is one of Britain's leading actors, so much so that he was voted into the Top "100 Greatest Britons" in a 2002 poll sponsored by the BBC. Crawford began his acting career as a seven-year-old, appearing in the première of Benjamin Britten's work for children, Let's Make an Opera. Although he most often appears in musicals, he became known to millions for his role as the hapless Frank Spencer in the television sitcom, Some Mothers Do 'Ave 'Em, for which he performed most of his own stunts. It was one of the BBC's most successful series of all time.

Crawford has played leading roles in films such as Hello, Dolly (1968), but more often appears on stage, having starred in West End productions such as Billy (based on the novel, Billy Liar) (1974), Barnum (1981) (one of the longest runs by a leading man) and, most notably, Andrew Lloyd Webber's Phantom of the Opera (1986).

Michael David Crawford is a software consultant in the United States, having operated the company GoingWare Inc. since 1998. He graduated with a B.A. in Physics from UCSC in 1993 and studied earlier at Caltech. He is also an artist, musician and writer.

He occasionally receives adoring fan mail from heart-sick women who suffer from poor reading comprehension.
