Frederick Roger Imhoff (later Imhof) was born August 15, 1875 in Rock Island, Illinois. Imhof entered show business in the 1890s, initially as a clown with the Mills Orton Circus and then in comedic contortion and acrobatic burlesque acts with Charles Osborne.

In the early 1900s, Imhof paired up with Hugh Conn as a two-man act. The duo was soon joined by Marcelle Corinne (sometimes written Correen), who also married Imhof around 1913. In addition to touring as Imhof, Conn & Corinne, Imhof toured with a number of larger vaudeville and burlesque companies, including Robie's Knickerbockers.

Imhof became a film actor in Hollywood during the industry's early years, and is credited with 54 small roles in films from the 1930s through the 1950s. He also worked as a presenter and as an emcee. Imhof died in Hollywood, California on April 15, 1958 and is buried in Valhalla Memorial Park.
