(written from a Production point of view)
Norman Lloyd (born 8 November 1914; age 101) is the actor who played Professor Richard Galen in the sixth season episode of Star Trek: The Next Generation entitled "The Chase" in 1993. However, he is probably best known to television audiences for playing Doctor Daniel Auschlander on the drama series St. Elsewhere from 1982 through 1988. Among his co-stars on this popular series were fellow Trek actors Ed Begley, Jr., Ronny Cox, Chad Allen, Jane Wyatt, France Nuyen, Brian Tochi, Deborah May, Alfre Woodard, David Birney, and Bruce Greenwood.
Lloyd began his career in show-business performing in theater before Alfred Hitchcock cast him as Frank Fry in the 1942 film, Saboteur (which co-starred Ian Wolfe). He would work with Hitchcock again in the latter's 1945 masterpiece, Spellbound, before being assigned as a producer on Hitchcock's anthology series, Alfred Hitchcock Presents (later The Alfred Hitchcock Hour). Lloyd would also direct as well as appear in episodes of the program, and from this point until 1979, Lloyd not only continued to act, but to produce and direct for television and for the stage, as well.
As an actor, Lloyd has appeared in several popular films. Most notable among these are A Walk in the Sun (1945), The Southerner (1945), The Green Years (1946, with Dean Stockwell), Reign of Terror (1949, with Arnold Moss), Charlie Chaplin's Limelight (1952, with Leonard Mudie), Audrey Rose (1977, directed by Robert Wise), Dead Poets Society (1989, with Kurtwood Smith), Amityville: The Evil Escapes (1989 TV movie, with Jane Wyatt, Aron Eisenberg, and Warren Munson), Kubato (1992, with John Rhys-Davies), The Age of Innocence (1993), The Adventures of Rocky & Bullwinkle (2000, with Jason Alexander, Whoopi Goldberg, and Max Grodénchik), and the 2000 made-for-TV movie Fail Safe (with James Cromwell and Bill Smitrovich). He most recently had a supporting role in the 2005 romantic comedy In Her Shoes.
Lloyd also had recurring roles in the television series Wiseguy and The Practice, and was a regular on the science fiction series Seven Days from 1998 through 2000, alongside Alan Scarfe. Other series he has appeared on include Kojak, Murder, She Wrote, Wings (starring Steven Weber), and Quincy, M. E. (starring Garry Walberg and Robert Ito).
Having celebrated his 101st birthday on 8 November 2015, Lloyd is the oldest living known actor to have appeared in the Star Trek franchise, following the death of Star Trek: Voyager guest star Olaf Pooley in July 2015. He is only the fourth Star Trek performer to reach the age of 100, following Viola Stimpson, Ellen Albertini Dow, and Olaf Pooley.
