Leonard Nimoy is an American actor, film director, poet, musician, and photographer. Nimoy's most famous role is the half-Vulcan, half-human Spock from Star Trek: The Original Series, which ran from 1966 to 1969. He earned three Emmy nominations for playing this character. Nimoy went on to reprise Spock's character in a voice-over role in Star Trek: The Animated Series, two episodes of Star Trek: The Next Generation, and six Star Trek motion pictures featuring the original cast.

Before his success in Star Trek, Nimoy had acted in more than 50 movies or television shows. After the cancellation of the original Star Trek series, Nimoy immediately joined the cast of the spy series Mission: Impossible. He co-starred with Yul Brynner and Richard Crenna in Catlow (1971) and appeared in various made-for-TV films, such as Assault On The Wayne (1970), Baffled (1972), The Missing Are Deadly (1974), and Marco Polo (1982). He received an Emmy award nomination for best supporting actor for the TV film A Woman Called Golda (1982).

After directing a few TV episodes, Nimoy broke into film directing in 1984 with the successful third installment of the Star Trek film series, Star Trek III: The Search for Spock. Nimoy would go on to direct the most successful film in the franchise to date, Star Trek IV: The Voyage Home (1986), and move beyond the Trek universe with Three Men and a Baby, the highest grossing film of 1987. Nimoy also did occasional work as a voice actor in animated feature films including the character of Galvatron in The Transformers: The Movie (1986) and The Pagemaster (1994).

In 1994, Nimoy began to narrate the Ancient Mysteries series on A&E, including "The Sacred Water of Lourdes" and "The Last Days of the Romanovs." He had a central role in Brave New World, a 1998 TV film adaptation of Aldous Huxley's novel. Nimoy has also "appeared" in the popular animated series Futurama and The Simpsons, as both himself and Spock. During and following Star Trek, Nimoy also released five albums of vocal recordings on Dot Records, including Trek-related songs such as "Highly Illogical," and cover versions of popular tunes such as "Proud Mary."

In 2003, Nimoy announced his retirement from acting in order to concentrate on his photography. However, it was revealed in 2007 that Nimoy would return to reprise his famous role as Spock one more time in J. J. Abrams' Star Trek in 2009.
