Calvert DeForest , also known by his character Larry "Bud" Melman, passed away this past Monday.

DeForest is credited for 4 films from 1972 to 1982. After his first appearance with David Letterman, he appeared in 15 other films or television shows.

While he was working as a file clerk at a drug rehabilitation facility, DeForest was "discovered" by people associated with David Letterman's show when he appeared in a New York University student's film. Later, he worked as a drug rehabilitation counselor. His job was mentioned on air and it made it more difficult for him to work effectively as a counselor, forcing his retirement.

DeForest continued to make appearances with David Letterman. One of his "advertisements" on "Late Night" was "Toast On A Stick."

DeForest later appeared under his own name, but as essentially the same character, when Letterman moved from NBC to CBS in 1993 to do "The Late Show with David Letterman." This change was made because the character of Larry "Bud" Melman was considered the intellectual property of NBC, even though David Letterman gave him the name.

DeForest continued to appear on Letterman's show until 2002. He also had a recurring role during the first season of Pee-Wee's Playhouse, before he retired from acting.
