justacarguy.blogspot.com: the Dilbert comic strip character from Scott Adams (from the 1990's to present), was named for the character Dilbert Groundloop in WW2 Navy aviation training manuals. Those are related to the Army training films by Dr Suess, Chuck Jones, Mel Blanc, and Frank Capra and also the training manuals by Will Eisner

Dilbert Goundloop was a doofus, where IMHO Adams' Dilberrt is an M. Mouse everyman figure.
