(NEW YORK) — Ron Palillo, who played Arnold Horshack on Welcome Back Kotter, has died, according to The Palm Beach Post. He was 63.
Friends tell the paper that Palillo passed away at his home in Palm Beach Gardens, Fla., Tuesday morning.
TMZ reports that Pallilo died of a heart attack. According to the site, he was found by his partner of many years, Joseph Gramm, early Tuesday morning. Gramm called an ambulance, and the actor was rushed to the hospital, where he was pronounced dead.
Palillo’s death comes just months after Bobby Hegyes, who played Juan Epstein on the show, passed away earlier this year.
Palillo’s Horshack was one of the most memorable characters on Welcome Back Kotter, thanks to his catchphrase “Ooh, ooh! Mr. Kotter!” and his distinctive, hyena-like laugh.
After Kotter, Palillo had other supporting TV roles, provided the voice for some animated shows such as Darkwing Duck, and in 1996, he played himself in a few episodes of the TV show Ellen. He also created the artwork for two children’s books, and appeared onstage in productions of Amadeus and Guys and Dolls. His first play, The Lost Boy, was produced in 2005.
In recent years, Palillo had been a teacher at the G-Star School of the Arts for Motion Pictures and Broadcasting.
