The son of the late actor who played the iconic Mr. Spock on the science fiction franchise “Star Trek” told the New York Post on Friday that his father loved speaking Yiddish.

Adam Nimoy recounted this tidbit about his father, Leonard Nimoy, with the release of  the documentary “For the Love of Spock,” which the latter directed.

It was in keeping with an interview Leonard Nimoy gave in 2014, in which he revealed that he had come up with the famous Vulcan salute for “Live long and prosper” after seeing it performed in synagogue during the traditional “Priestly Blessing” — Birkat Kohanim.

He also said that his Jewish identity influenced his approach to his famous “Star Trek” character in general:

Spock is an alien, wherever he is. Because he’s not human. He’s not Vulcan. He’s half and half — what we used to call a half-breed. … He’s not totally accepted in the Vulcan culture because he’s not totally Vulcan. Certainly not totally accepted in the human culture because he’s part Vulcan. And that alienation was something I learned in Boston. I knew what it meant to be a member of a minority — and in some cases, an outcast minority. So I understood that aspect of the character, and I think it was helpful in playing him.

Adam Nimoy said that his father “never forgot where he came from” and often visited Boston, where he grew up as the son of poverty-stricken, Orthodox Jews from Russia. The documentary was released on Friday, a year and a half after Leonard Nimoy died of lung disease at the age of 83.
