Mr. Spock’s Widow Puts on a Show

In the lobby, large letters spelled out “Live Long and Prosper,” Leonard’s catchphrase from a half century playing Mr. Spock from “Star Trek.” “It’s from the Jewish tradition,” Bay Nimoy said.

Leonard, who grew up Orthodox, in Boston, thought of the Birkat Kohanim, a prayer said by priests with their fingers spread apart. “The priest in the temple would go blah-blah-blah-blah-blah in Hebrew to bless the congregation,” she said, making Spock V’s with her hands. “It meant, essentially, May peace be with you.”
