Legendary actor Leonard Nimoy, known best for his role as “Spock” in the original Star Trek series, died Friday at the age of 83. Nimoy was born in Boston on March 26, 1931.

Mayor Marty Walsh says in a statement:

With the passing of Leonard Nimoy, we have not only lost a talented actor, but a proud product of Boston’s neighborhoods and English High School. Mr. Nimoy never forgot his Boston roots and the spirit of his work lives on in the future generations of children who continue to be inspired by his iconic portrayal of Mr. Spock.

President Barack Obama also commented on Nimoy’s death, issuing the following statement Friday afternoon:

Long before being nerdy was cool, there was Leonard Nimoy. Leonard was a lifelong lover of the arts and humanities, a supporter of the sciences, generous with his talent and his time. And of course, Leonard was Spock. Cool, logical, big-eared and level-headed, the center of Star Trek’s optimistic, inclusive vision of humanity’s future.

I love Spock.

In 2007, I had the chance to meet Leonard in person. It was only logical to greet him with the Vulcan salute, the unversal sign for “Live long and prosper.” And after 83 years on this planet – and on his visits to many others – it’s clear Leonard Nimoy did just that. Michelle and I join his family, friends, and countless fans who miss him so dearly today.
