President Barack Obama has paid tribute to Leonard Nimoy who died today, aged 83.
Releasing an official statement on the passing of the much-loved actor, the US President said he "loved Spock."
"Long before being nerdy was cool, there was Leonard Nimoy," said Obama. "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."
Recalling an occasion when he met the actor in person he said: "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."
William Shatner, who played Captain Kirk in the hit US series Star Trek, paid an emotional tribute to his co-star and close friend. He said: "'I loved him like a brother. We will all miss his humour, his talent, and his capacity to love.'"
The relationship between the Captain of the Enterprise and his second-in-command is a central feature of the Star Trek series, and just as Kirk and Spock shared a loyal bond, Shatner and Nimoy forged a close real-life friendship. Nimoy was even best man at Shatner's wedding in 2000.
Star Trek actor George Takei, who played Sulu in the original series, paid an emotional tribute to his friend saying he would miss him in "many, many ways".
"Today, the world lost a great man, and I lost a great friend. We return you now to the stars, Leonard. You taught us to "Live Long And Prosper," and you indeed did, friend. I shall miss you in so many, many ways."
Rest in peace with the stars, my dear friend. pic.twitter.com/D2dVG6I9Xi

Will Wheaton from Star Trek: The Next Generation wrote: "We stood on your shoulders, and wouldn't have had a galaxy to explore if you hadn't been there, first. Thank you, Leonard, Rest in peace."
David Baddiel wrote poignantly: "Leonard Nimoy dying seems somehow...illogical."
