He passed away on 28 October (12) after suffering a heart attack near his home in Northridge, California.
Brunner launched his career as a publicist in the early 1960s, working with stars including Tony Bennett and Louis Armstrong, and moved into TV by writing for 1970s series The Odd Couple, which was executive produced by Garry Marshall, who worked with the writer on several occasions.
Brunner went on to pen scripts for Laverne & Shirley and Blansky's Beauties, two other series created by Marshall.
The writer then penned 15 episodes of Marshall's hit show Happy Days and produced 37 installments - as well as inventing the nickname 'Fonzie' for Henry Winkler's biker character.
Brunner received a shared Emmy Awards nomination for Love, Sydney in 1982, in the Outstanding Comedy Series category.
The Hollywood Reporter claims that a private family service for Brunner was held on Tuesday (06Nov12) at Forest Lawn Memorial Park, where his wife Ann was laid to rest in 1987.
