Bob Ross - Check
Jean Shepherd - A very close 1st guess with Soupy Sales, then went on a bender with Jim Henson & Mel Blanc, the "is he known for childrens works" type question threw it for a loop. (edit:yup, his name is in there, he is now correctly known to the genie to have created childrens works as well as being a US 50's-70's TV & Radio personality.)
