The actor died in Texas on Tuesday after a long battle with illness, McKeon's spokesman Jeff Ballard told People magazine.
“We are all beyond heartbroken and devastated over Phil’s passing,” said Ballard in a statement to the outlet. “His wonderful sense of humor, kindness and loyalty will be remembered by all who crossed his path in life.”

After "Alice" ended, McKeon went on to star in a handful of other projects. His last on-screen appearance was 1994's "Ghoulies IV." He also directed a film and produced several others, including "Teresa's Tattoo," which starred his sister.
