He had a full, rich life. Born in Boston's West End to Ukrainian Jewish parents, he was raised in a tenement and roamed the streets of Boylston and the Fens, selling newspapers as a boy. He saw the Red Sox play at Fenway Park and learned to row on the Charles River. He was a man of whom nothing negative was said of his character, and William Shatner called him the brother he never had.
I fell in love with Star Trek as a child and my love for the show has been with me all my life. It fueled dreams in me, and it brought me to modern fandom. My first slash love was Kirk/Spock, easy because of the depth of warmth and affection between the characters that we saw on a weekly basis. It was my 'gateway' fandom, as it was for so many. Through fandom I found my true outlet for creativity and made so many friends! I have been very happy in fandom all these years.
Star Trek and Mr. Spock is part of the cultural language and an actor could do a lot worse than be known for a character with such impact on so many people's lives. When you inspire people to become scientists and astronauts, you're doing pretty well. I can see The Big Bang Theory, which he guest-starred on, to come up something soon. :)
Rest in peace, Mr. Nimoy. You lived long and prospered.
