4864 Nimoy           Discovered 1988 Sept. 2 by H. Debehogne at the European Southern Observatory.
Leonard Nimoy (1931-2015) was an American actor, film director and poet. Best known for his portrayal of the half-Vulcan/half-human science officer Spock in the original "Star Trek" TV series and subsequent movies, Nimoy wrote two autobiographies: I Am Not Spock (1975) and I Am Spock (1995).
