He was blessed with remarkably gifted art assistants over the years, including Bob Donovan, Bobbie Swain, Beau Break, Ping Chen, Wendolyn Bocardo, John R. Rose who was chosen to take over the production of Snuffy, for King Features Syndicate, and other young Tampa Artists as well as the students he mentored. Cartoonist Bob Donovan worked with Lasswell for the longest stretch. Bob Donovan was one of the great old guard cartoonists who, like Lasswell, had the genuine artistic ability to translate almost any situation into a subtle style of humor that brings levity, laughter, and forgiveness to humanity.
