Actor Leonard Nimoy, best known for playing the role of Spock in the "Star Trek" movies and television series, has died at age 83 in Los Angeles. 

Earlier this week Nimoy was taken to the hospital and treated for lung disease, Fox News reported. 

One of Nimoy's grandchildren posted the announcement from Nimoy's Twitter account.

Check out some reaction to the passing of the iconic actor.

 

President Barack Obama released a statement on the passing of Nimoy:

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 loved Spock.

In 2007, I had the chance to meet Leonard in person.  It was only logical to greet him with the Vulcan salute, the universal 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.
