Harlan Ellison, the outspoken, prolific author of stories, novels, screenplays, TV, and comics, died in his sleep this morning at the age of 84. Ellison wrote many a beloved and thought-provoking SF story including Trek‘s “The City on the Edge of Forever,” and won, in the words of Rick Green, “every coveted award– except Miss Congeniality.” Stephen King opined today that “If there’s an afterlife, Harlan is already kicking ass and taking down names.” John Scalzi has offered his own perspective on the irascible Mr. Ellison.

SF will miss him.
