Although impressive, Dennis Koenig's career in television is relatively unknown despite his having worked on some of the most popular, well-loved television shows of the 1970s and '80s. Serving as a producer, writer, and/or story editor, Koenig contributed his skills to such classic sitcoms as "Rhoda", "The Jeffersons", "Three's Company", and "Barney Miller". However, his tenure on the beloved ensemble series "M.A.S.H." is arguably his most notable work as a multi-talented behind-the-scenes player. Koenig's involvement with the show lasted five seasons. The venerable, Korean-War-set medical dramedy's follow-up, "After MASH", was a misstep and did not catch on with viewers, but Koenig's subsequent work in the 1980s as both a writer and story consultant on the popular, circus-like sitcom "Night Court" (which reunited him with "Miller" writer Reinhold Weege) was far more fruitful. Koenig also worked on the family sitcom "Growing Pains" and "Anything But Love", the latter of which starred Richard Lewis and Jamie Lee Curtis. Koenig disappeared from the television scene sometime in the early 1990s.
