From Wikipedia, the free encyclopedia Lou Tellegen (born Isidor Louis Bernard Edmon van Dommelen, November 26, 1881 – October 29, 1934) was a Dutch-born silent film and stage actor, film director and screenwriter. Tellegen made his stage debut in Amsterdam in 1903, and over the next few years built a reputation to the point where he was invited to perform in Paris, eventually co-starring in several roles with Sarah Bernhardt, with whom he was involved romantically.

In 1910, he made his motion picture debut alongside Bernhardt in La dame aux camélias, a silent film made in France. In the summer of 1913, Tellegen went to London where he produced and starred in Oscar Wilde's play The Picture of Dorian Gray. Invited back to the United States, Tellegen worked in theatre and made his first American film in 1915, titled The Explorer, followed by The Unknown.
