Richard Dysart wasn't just another face on TV. He was the gravity in the room. If you grew up watching L.A. Law, he was Leland McKenzie—the steady, moral compass of a firm that often felt like it was spinning out of control. When news broke that he had passed away, it felt like losing a distant, reliable uncle.
He died at home. Santa Monica, California. It was April 5, 2015.
He was 86 years old, a respectable run for a man who spent decades playing presidents, generals, and power brokers. But for a while, the specifics were a bit vague. People knew he’d been away from the spotlight, but the "how" and "why" took a moment to surface through the typical Hollywood press releases.
The Reality of the Richard Dysart Cause of Death
Honestly, it wasn't a sudden shock or a freak accident. Richard Dysart died after a long battle with cancer.
His wife, the artist Kathryn Jacobi, confirmed the news shortly after he passed. While some initial reports simply cited a "long illness," it was eventually clarified that cancer was the culprit. He had been fighting it for a while, away from the prying eyes of the tabloids. That was very much his style—low-key, dignified, and private.

He didn't want a spectacle.
It's kinda interesting how he played these invincible authority figures on screen, yet in his final years, he was dealing with the same grueling health battles as anyone else. He spent his final moments at his home in Santa Monica, surrounded by family. No hospital tubes, no cold linoleum floors. Just home.
A Legacy Beyond the Diagnosis
You can't talk about his death without talking about the life that preceded it. Dysart was a "character actor" in the truest sense, though that term sometimes feels like a backhanded compliment. He was a chameleon.
Before he was Leland McKenzie, he was a fixture in some of the most iconic films of the 70s and 80s. Remember The Thing? He was Dr. Copper. He was the guy who had his arms bitten off by a chest-cavity-mouth in one of the wildest practical effects scenes in cinema history.

Think about that range. One day he’s the patriarch of a prestige legal drama, the next he’s in a John Carpenter horror flick getting maimed by an alien.
Key Career Milestones
- L.A. Law: He appeared in every single episode. All 171 of them.
- The Emmy: He won for Outstanding Supporting Actor in 1992.
- The Stage: He was a founding member of the American Conservatory Theater.
- Historical Figures: He played Harry S. Truman and Dwight D. Eisenhower. Multiple times.
He had this voice. It was deep, resonant, and commanded immediate respect. It’s why he was cast as the "boss" so often. In Oliver Stone’s Wall Street, he played the CEO of BlueStar Airlines. He was the one Gordon Gekko was trying to crush. Even standing across from Michael Douglas at his most manic, Dysart held his ground.
Why We Still Talk About Him
There’s a reason why search terms for the Richard Dysart cause of death still pop up. He represented a specific era of television where the "adults in the room" actually felt like adults.
He was also a pioneer in a way most people forget. On L.A. Law, his character Leland McKenzie started wearing a hearing aid. This wasn't some scripted gimmick; Dysart actually needed one in real life. By incorporating it into the show, he helped de-stigmatize something millions of people deal with but feel embarrassed about.

He told the Associated Press back in 1988 that he thought people just "put up with not hearing" because of the shame. He decided to just wear the damn thing on camera. That's a small detail, but it says a lot about the man's character.
Final Days in Santa Monica
By the time 2015 rolled around, Dysart had been retired from on-screen acting for about thirteen years. His last major credit was reprising his role in L.A. Law: The Movie in 2002. He spent those final years focused on his family and his life with Kathryn.
Cancer is a thief, but it didn't take his legacy.
When he died, the tributes didn't just come from fans—they came from the heavy hitters of the industry. Steven Bochco, the creator of L.A. Law, spoke about his "quiet strength." He wasn't the guy chewing the scenery or demanding the spotlight. He was the anchor.
If you’re looking to honor his memory or dive deeper into his work, skip the legal briefs for a second. Go watch him in Being There (1979) alongside Peter Sellers. He plays a doctor—again—but the nuance he brings to a man trying to understand an impossible situation is a masterclass in subtlety.
Actionable Takeaways for Fans
- Revisit the Classics: If you only know him from L.A. Law, watch The Thing or Pale Rider. The contrast is shocking.
- Support Cancer Research: Given that cancer was the cause of his passing, supporting organizations like the American Cancer Society is a direct way to honor his struggle.
- Appreciate the "Anchors": Next time you watch a show, look for the actor holding the scene together without saying much. That was Dysart's gift.
He left behind a wife, a stepson, and a body of work that spans the golden age of theater and the peak of network television. Richard Dysart didn't just play authority figures; he earned the authority he projected.
