TMZ has reported the sad news that "Welcome Back, Kotter" has suffered its second loss in a year as Ron Palillo, the actor who played Horshack, passed away this morning near Palm Beach, Florida, from an apparent heart attack.
Palillo was apparently found by his partner, Joseph Gramm, around 4:00 a.m. Palillo was rushed to a nearby hospital, where he was pronounced dead at 63 years old.
Palillo was best known for playing Arnold Dingfelder Horshack on Welcome Back, Kotter, but he did also appear on Ellen, Darkwing Duck, Laverne and Shirley in the Army and he appeared in Friday the 14th Part VI: Jason Lives.
Here are some clips of him in action, on Welcome Back, Kotter; in an MTV spoof; and against Dustin Diamond in a boxing match:
In recent years, Palillo taught at G-Star School of the Arts for Motion Pictures and Broadcasting in Palm Beach County, Florida. He also produced his first full-length play, the Lost Boy, in 2005 and, in 2007, he introduced a clothing line spcializing in limited-edition t-shirts created by Rotter and Friends.
Earlier this year, "Kotter" co-star Robert Hegyes, who played Epstein, also passed away, also from a heart attack.
