It’s kind of wild to think about how a sitcom about a bunch of remedial students in Brooklyn could change television history, but here we are. Welcome Back, Kotter wasn't just another 70s show. It was a cultural lightning bolt that basically gave us John Travolta and made "Up your nose with a rubber hose" a household phrase.
But honestly, if you look at the cast of Welcome Back Kotter today, it’s a bittersweet story. You've got massive Hollywood icons, world-class poker players, and sadly, quite a few empty seats at the reunion table.
The Star Power of Vinnie Barbarino
Let’s start with the obvious. John Travolta.
Before he was dancing in Pulp Fiction or flying his own planes, he was Vinnie Barbarino. He was the "leader" of the Sweathogs, though mostly he was just the guy with the hair and the dimples. It’s funny because Robert Hegyes (who played Epstein) actually thought he was cast as Barbarino until he met Travolta in an elevator on the first day. Imagine that ego bruise.
Travolta’s trajectory is basically unmatched. He’s one of the three surviving main cast members. Even in 2026, he’s still headlining projects, with rumors of Face/Off 2 and a string of indie thrillers like High Rollers keeping him in the spotlight. He’s the guy who proved a sitcom could be a legitimate springboard to the A-list.

Gabe Kaplan: From Teacher to Poker Pro
Gabe Kaplan is a fascinatng case. He didn't just play Mr. Kotter; he co-created the show based on his own stand-up routine and his real-life experiences at New Utrecht High School.
By the fourth season, things got messy. Kaplan had major contract disputes with the executive producer, which is why Mr. Kotter basically disappears for long stretches of the final year. He’s eventually "promoted" to vice principal just to keep him in the credits.
But check this out: after the show, he didn't really chase the Hollywood dragon. He became an elite poker player. We’re talking nearly $2 million in live tournament winnings and a legendary stint as a commentator for High Stakes Poker. At 80 years old, he’s still one of the most respected names in the gambling world. Talk about a second act.
The Sweathogs We’ve Lost
This is where the nostalgia gets a little heavy. Most of the original crew passed away far too young, often in their early 60s.
- Robert Hegyes (Juan Epstein): He was the heart of the group, always handing Kotter those fake notes signed by "Epstein’s Mother." Hegyes was actually a classically trained actor and later became a teacher himself at Rowan University. He died of a heart attack in 2012 at age 60.
- Ron Palillo (Arnold Horshack): Who could forget that laugh? Hyeh-hyeh-hyeh. Palillo struggled with being typecast—it's tough to get serious roles when everyone expects you to raise your hand and yell "Ooh! Ooh! Ooh!" He eventually found peace as a stage director and a talented illustrator. He passed away just months after Hegyes in 2012, also from a heart attack, at 63.
- Marcia Strassman (Julie Kotter): She was the grounding force of the show. She went on to star in Honey, I Shrunk the Kids, but she fought a long, brave battle with breast cancer before passing away in 2014.
Lawrence Hilton-Jacobs: Still Boom-Booming
Lawrence Hilton-Jacobs, the man behind Freddie "Boom Boom" Washington, is the other major survivor. He’s stayed incredibly busy. You've probably heard his voice in The Proud Family: Louder and Prouder or seen him in the drama A House Divided.

Hilton-Jacobs always brought a certain coolness to the cast of Welcome Back Kotter that kept the show from feeling too goofy. He was the athlete, the "cool guy," and honestly, he’s still got that same charisma in his 70s.
Why the Show Stays Relevant
Why do we still care? Why is there a "Welcome to Brooklyn" sign in Borough Hall that looks exactly like the one from the opening credits?
It's because the show dealt with "remedial" kids—the ones the system had written off—and gave them a teacher who actually gave a damn. It was gritty for its time. It showed a Brooklyn that wasn't gentrified; it was loud, dirty, and full of heart.
Actionable Takeaways for Classic TV Fans
If you're looking to dive back into the world of the Sweathogs, here is how you can do it without just scrolling through Wikipedia:
- Watch the "Backdoor Pilot": Look for the episode "The Drop-In," which was supposed to spin off Horshack into his own series. It never happened, but it’s a weird piece of TV history.
- Check out the Art: Look up Ron Palillo’s illustrations for children's books like The Red Wings of Christmas. It shows a side of him the sitcom never allowed.
- The Poker Archives: If you want to see Gabe Kaplan’s real-life wit, watch old clips of him at the World Series of Poker. His "teacher" persona never really left him; he just traded the chalkboard for a deck of cards.
- Follow the Sign: If you’re ever in Brooklyn, visit Borough Hall to see the original "Welcome to Brooklyn" sign from the credits. It’s a holy grail for fans.
The cast of Welcome Back Kotter represents a specific era of television where chemistry mattered more than high-concept plots. While much of the cast has moved on or passed away, the impact they had on the "underdog" archetype in comedy is still felt in every classroom sitcom made today.

Next Steps:
To truly appreciate the legacy, you should seek out the 30th-anniversary reunion clips from the TV Land Awards. It was one of the last times the core group was all together, and the genuine affection between Kaplan and his "students" is unmistakable. If you're a collector, the complete series DVD set contains several "lost" promos that never aired during the original run.
