Brunner died of a heart attack on Oct. 28 near his home in Northridge, California.
Brunner got his start in the entertainment industry as a publicist in the early 1960s when he worked with Tony Bennett and Louis Armstrong. He then transitioned to TV writing for THE ODD COUPLE, executive-produced by his childhood friend Garry Marshall. The two frequently worked together, next when Brunner wrote for LAVERNE & SHIRLEY and then when he wrote 15 episodes and produced 37 episodes of HAPPY DAYS.
