Forrest J. Ackerman died December 4th 2008 at the age of 92. I didn't know him personally, but I knew his reputation.
He coined the term "sci-fi" and wore a homemade costume to the first World Science Fiction Convention in New York City in 1939. His collection of movie memorabilia and props was second to none. He was a writer, editor, literary agent and actor.
He was inclusive in his fandom and passionate to the end. In a time when one is quick to elevate one branch of fandom over others, it is important to remember that the first fandom was inclusive and diverse.
He was the giant that lifted my fandom up so I could see farther than I ever would have alone.
