Leonard Nimoy was one of those few people who, for me, just seemed like he'd be around forever; who it's very strange to think of existing on the same planet without, even though it's not as though I ever met him.

He did a lot of fantastic art. I loved that he ventured into photography, especially his body-positivity stuff such as The Full Body Project: http://www.amazon.com/The-Full-Body-Project-Photographs/dp/0979472725
