Hahahaha yeah that is the one everyone remembers and is certainly one of the best if not the best. I would also look into Curtis Fuller and of newer trombonists Wycliffe Gordon. Uhhhhhhhhhhhhhh other ones that I don't necessarily like but "of note" are Slide Hampton, Jack Teagarden, Tommy Dorsey (duh), Kid Ory (dixieland), Bill Waltrous, Steve Turre, Frank Rosolino, Kai Winding, John Allred, and Carl Fontana.
(whew)
