Leonard Simon Nimoy was born on March 26, 1931, in the West End of Boston, Massachusetts, the son of Jewish immigrants from Iziaslav, Ukraine. His parents left Iziaslav separately--his father first walking over the border into Poland while his mother and grandmother were smuggled out of the Soviet Union in a horse-drawn wagon by hiding under bales of hay. They reunited after arriving in the United States. His mother, Dora (nee Spinner) (1904-1987), was a homemaker, and his father, Max Nimoy (1901-1987), owned a barbershop in the Mattapan section of Boston.

Following Star Trek in 1969, Nimoy immediately joined the cast of the spy series Mission: Impossible, which was seeking a replacement for Martin Landau. Nimoy was cast in the role of Paris, an IMF agent who was an ex-magician and make-up expert, "The Great Paris". He played the role during seasons four and five (1969-1971). Nimoy had been strongly considered as part of the initial cast for the show, but remained in the Spock role on Star Trek. He co-starred with Yul Brynner and Richard Crenna in the Western movie Catlow (1971). He also had roles in two episodes of Rod Serling's Night Gallery (1972 and 1973) and Columbo (1973), season 2 episode 6 entitled "A Stitch in Crime"; Nimoy portrayed murderous doctor Barry Mayfield, one of the few murder suspects toward whom Columbo showed anger. Nimoy appeared in various made-for-television films such as Assault on the Wayne (1970), Baffled! (1972), The Alpha Caper (1973), The Missing Are Deadly (1974), Seizure: The Story Of Kathy Morris (1980), and Marco Polo (1982). He received an Emmy Award nomination for best supporting actor for the television film A Woman Called Golda (1982), for playing the role of Morris Meyerson, Golda Meir's husband, opposite Ingrid Bergman as Golda in her final role. In 1975, Leonard Nimoy filmed an opening introduction to Ripley's World of the Unexplained museum located at Gatlinburg, Tennessee, and Fisherman's Wharf at San Francisco, California. In the late 1970s, he hosted and narrated the television series In Search of..., which investigated paranormal or unexplained events or subjects. In 2000-2001 he hosted CNBC TV series The Next Wave With Leonard Nimoy, which explored how e-businesses were integrating with technology and the Internet. He also had a character part as a psychiatrist in Philip Kaufman's remake of Invasion of the Body Snatchers.
