Leonard Nimoy born 1931

Leonard Nimoy, born March 26, 1931 in Boston, Massachusetts, is best known for his portrayal of the Vulcan Mr. Spock in the Star Trek cinematic universe.  He played the character in the original series, the first five movies featuring the cast from the original series, and then appearances in some of the spin-off series and movies. He also directed, including Star Trek IV: The Voyage Home.  

He made his Hollywood debut at 20, in Queen for a Day in a bit part.  He appeared briefly in the sci-fi classic Them!.

He was nominated for four Primetime Emmys, three of which were for his role as Spock. On January 16, 1985, he was awarded a star on the Hollywood Walk of Fame.

He passed away in February 2015 from chronic obstructive pulmonary disease.

DeForest Kelly (Dr. "Bones" McCoy) born 1920

DeForest Kelly, born January 20, 1920 in Toccoa, Georgia, will always be remembered as the cantankerous Dr. Leonard "Bones" McCoy in the Star Trek universe.  He had appeared in many westerns prior to his casting on Star Trek and was more comfortable in that genre rather than science fiction.  Kelly passed away in 1999, the first of the original main cast from Star Trek.

McCoy wasn't one of my favorite characters on the series and movies but he did have some great moments.  

I love this one from Star Trek VI: The Voyage Home:
