Frederick Hallen was a Canadianborn vaudeville entertainer who found popularity on the North American stage.
Frederick Fred Hallen was born in Montreal, Canada. He began touring the vaudeville circuit as early as 1880 with his American wife Enid Hart, as Hallen and Hart. A year or so before she died in 1890 at the young age of 32, he teamed up with Joseph Hart, as Hallen and Hart , and found success touring for several seasons with Harts musical comedies, Later On and The Idea. After the two went their separate ways, Hallen and his second wife, Mollie Fuller, the sister of dancer Loie Fuller, became a headlining vaudeville act. Hallen and Fuller were known for their short comedic plays and skits performed in vaudeville houses across North America for nearly a quarter century.
