Claimed to have been born Prince Michael Dimitri Alexandrovich
Obolensky-Romanoff, nephew of Tsar Nicholas II. Everyone in Hollywood knew he
wasn't, but, in a town full of pretenders, it hardly mattered, and
"Prince Michael" enjoyed great success as a restaurateur.
Was a pallbearer at Errol Flynn's funeral along with Raoul Walsh, Mickey Rooney, Guinn "Big Boy" Williams, Jack Oakie, and Otto Reichow October 19, 1959 at the Church of the Recessional at Forest Lawn, Glendale, CA.
From 1941 to 1962, Mike Romanoff's Beverly Hills restaurant Romanoff's was considered the top spot for international cuisine in Hollywood, and was frequented by many movie stars. Its menu introduced such delicacies as foie gras, frog's legs and turtle soup to the region.
Changed his name to Harry F. Gerguson some time after 1900.
