(written from a Production point of view)
Joseph Ruskin (14 April 1924 – 28 December 2013; age 89) (born Joseph Richard Schlafman) was an American actor who appeared in every Star Trek television series except Star Trek: The Next Generation (although he did appear in Star Trek: Insurrection). With the exception of Majel Barrett, who has appeared in every Star Trek series, he was the only actor to appear in all four of the series in question. Furthermore, given that Barrett only provided the computer voice in Star Trek: Deep Space Nine and Star Trek: Voyager, Ruskin was the only actor to appear on screen in all four series mentioned above. Along with Majel Barrett, Clint Howard, Jack Donner and Vince Deadrick, he was one of only five actors to appear in both Star Trek: The Original Series and Star Trek: Enterprise. He, Barrett and Howard also appeared in DS9.
Hailing from Haverhill, Massachusetts, USA, he was born as Joseph Schlafman. Ruskin, like William Schallert, Barry Gordon and Kitty Swink served on the Screen Actors Guild Executive Board of Directors, becoming a Trustee at the Screen Actors Guild Pension and Health Plan. Ruskin worked for the SGA between 1976 and 1999.
He had a long and distinguished career, appearing in television series as early as 1959. More recently, he had a recurring role as Alliance Member Alain Christophe in J.J. Abrams' series Alias, as well as playing an elderly mob boss in Smokin' Aces, which featured Chris Pine.
