(written from a Production point of view)
Felix Maurice Locher (16 July 1882 – 13 March 1969; age 86) was an actor who portrayed Robert Johnson in the 1967 Star Trek: The Original Series episode "The Deadly Years". He filmed his scenes on Thursday 3 August 1967 at Desilu Stage 9 and Stage 10.
Locher died in Hollywood, California at the age of 86. His death occurred one day before the penultimate TOS episode, "All Our Yesterdays", aired. Along with Judith Anderson, Morgan Farley, Richard Hale, Anthony Jochim, Celia Lovsky, Leonard Mudie, Charles Seel, Abraham Sofaer, and Ian Wolfe, he is one of only ten credited Star Trek guest stars born in the 19th century to appear in any episode or film. Locher is also the earliest born Star Trek performer.
Swiss born Felix Locher started his acting career late in life, when he was already 73. He was visiting his son, film and television actor Jon Hall, on the set of Hell Ship Mutiny (1957), when the director spotted him and convinced him to play the part of a Tahitian chief in the feature. Prior to his acting career, Locher had worked as an insurance salesman as well as an inventor, with over 100 copyrights and patents to his name.
Locher appeared in numerous television series and movies throughout the 1950s and 1960s. In 1963, he appeared alongside fellow TOS guest star Georgia Schmidt in House of the Damned. He also appeared in a three-part episode of the western series Branded entitled "Call to Glory", co-starring fellow TOS actors Robert Lansing and Richard Tatro. He remained active as an actor until his death in 1969, as he appeared in two other productions, the television series Gunsmoke and Love, American Style, after his performance on Star Trek.
His son Jon, very much responsible for his father's acting career, died in 1979 and is buried next to his father in Forest Lawn Cemetery in Hollywood Hills.
