Biff Brannon was a gentle hearted restaurant owner/manager in the book The Heart Is A Lonely Hunter
by the late Carson McCullers.
Set in a Georgia milltown in the 1930s, a highly enjoyable reading experience, which can educate people about various aspects of bigotry.
Then there was good natured Biff Baker, portrayed by Alan Hale Jr. in the early 1950s television series Biff Baker, USA
I used the name Biff for one of my continuing characters in an ongoing series of police department mystery novels. A decent fellow, residing and working in Pittsburgh, Pennsylvania.
