(written from a Production point of view)
Locher appeared in numerous television shows and movies throughout the 1950s and 1960s. In 1963, Locher 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 was the father of fellow film and television actor Jon Hall (born Charles Felix Locher).
Locher died in 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 also is the earliest born Star Trek performer.
