(written from a Production point of view)
Herbert "Herb" Kenwith (14 July 1917 – 30 January 2008; age 90) was a Hollywood television director and producer. In 1968, he directed the Star Trek: The Original Series third season episode "The Lights of Zetar", which aired in January the following year.
Hailing from New Jersey, Kenwith had a long career on Broadway as well as in regional theater before turning to television. On Broadway, he was an assistant stage manager and performer in the original production of I Remember Mama, which ran for 713 performances between 1944 and 1946 and marked Marlon Brando's Broadway debut. Kenwith later produced the original Broadway production of Me and Molly, which ran for 156 performances in 1948 and featured David Opatoshu in the cast. After Broadway, Kenwith produced and directed 65 plays for Princeton University's McCarter Theater. Among the performers he worked with during this time was Lucille Ball, who later tapped Kenwith as a director on her show, Here's Lucy.
The majority of Kenwith's television directing credits are sitcoms, including Mary Tyler Moore, Sanford and Son, Good Times, Gimme a Break! and Bosom Buddies. He also directed and produced the entire first season of Diff'rent Strokes, which began airing in 1976. Other shows he directed and produced include One Day at a Time, The Facts of Life, and the short-lived NBC series Joe's World, which starred K Callan.
Kenwith was a personal friend of Lucille Ball, and asked her if he can direct an episode of Star Trek. The cast and crew were surprised on how well and easily Kenwith directed the episode, despite his inexperience with filmed drama series (his television credits mostly being sitcoms).

The many other Star Trek actors whom Kenwith has directed throughout his career include Alan Oppenheimer (in an episode of The Partridge Family and an episode of Temperatures Rising), Julie Cobb (in an episode of Love, American Style), Richard Libertini (in an episode of Mary Tyler Moore), John Fiedler (in an episode of Temperatures Rising), Graham Jarvis (also in an episode of Temperatures Rising), Ron Glass (in an episode of Good Times and an episode of Sanford and Son), Thalmus Rasulala (in two episodes of Good Times), Don Marshall (also on Good Times), Fran Bennett (in an episode of Diff'rent Strokes), Elinor Donahue (also on Diff'rent Strokes), Joseph Campanella (in an episode of The Brady Brides), Charlie Brill (in an episode of One Day at a Time), John Putch (also on One Day at a Time), and Madge Sinclair (on Grandpa Goes to Washington). Kenwith also directed TOS guest actor Stanley Adams in an unsold pilot movie called Tiger, Tiger. He later directed another TOS alum, Jason Evers, in the 1973 made-for-TV movie Shadow of Fear, and directed Walker Edmiston in an unsold 1975 pilot called Home Cookin'.
