Bonanza wasn’t just another western — it was a cultural institution. Premiering on NBC in September 1959, it became the second-longest-running western series in American television history, trailing only Gunsmoke. Over 14 seasons and 431 episodes, the show followed the Cartwright family — a widowed patriarch and his three grown sons — as they ran the sprawling Ponderosa ranch near Virginia City, Nevada, with Lake Tahoe’s stunning backdrop serving as their fictional backyard.
What made Bonanza stand apart from every other western on TV? It was the first series to be broadcast entirely in color on NBC, a bold move at a time when most American households still watched black-and-white sets. That decision paid off handsomely — the show topped the Nielsen ratings for three consecutive seasons in the mid-1960s and remained a top-ten fixture for most of its run.
But the real draw was always the Cartwrights themselves. Ben, Adam, Hoss, and Little Joe weren’t just cowboys solving crimes of the week. They were a family, and audiences tuned in every Sunday night to watch them argue, reconcile, and protect one another. Sadly, every principal cast member has since passed away. Here’s what happened to the stars of Bonanza after the cameras stopped rolling.
Lorne Greene — Ben Cartwright
Lorne Greene was the anchor of Bonanza from its very first episode. As Ben Cartwright, the wise and commanding patriarch of the Ponderosa, Greene brought a warmth and authority that held the entire show together. Born in Ottawa, Canada, in 1915, he’d already built a distinguished career in Canadian broadcasting before Hollywood came calling. During World War II, his deep, resonant voice earned him the nickname “The Voice of Doom” while reading wartime news bulletins on CBC Radio.
Greene appeared in all 431 episodes of Bonanza, the only cast member who could make that claim. When the show ended in 1973, he moved quickly to his next project — the short-lived ABC crime drama Griff, which lasted just 13 episodes. He narrated the wildlife documentary series Last of the Wild and earned a memorable supporting role in the landmark 1977 miniseries Roots.
His biggest post-Bonanza role came in 1978 when he was cast as Commander Adama in Battlestar Galactica. The sci-fi series gave Greene a whole new generation of fans, even though it lasted only a single season. Through the late 1970s and early 1980s, he also became widely recognized as the spokesman for Alpo dog food commercials.
Greene returned to Canadian television in the 1980s, devoting much of his time to wildlife and environmental causes. He hosted the nature series Lorne Greene’s New Wilderness on CTV. He reunited with former Bonanza co-star Michael Landon for a guest appearance on Highway to Heaven shortly before his health declined. Lorne Greene died on September 11, 1987, at age 72, following complications from pneumonia after surgery for a perforated ulcer.
Pernell Roberts — Adam Cartwright
Pernell Roberts played Adam, the eldest and most intellectual of the Cartwright sons, but he was also the first to leave. After six seasons, Roberts departed Bonanza in 1965, making no secret of his dissatisfaction with what he considered formulaic scripts and shallow character development. It was a controversial decision at the time — walking away from one of the highest-rated shows on television.
Born in Waycross, Georgia, in 1928, Roberts had trained as a serious stage actor and always saw himself as more than a TV cowboy. After leaving the Ponderosa, he returned to Broadway, touring with Ingrid Bergman in Captain Brassbound’s Conversion in 1972. He earned a Joseph Jefferson Award nomination for his performance in Welcome Home the following year.
Roberts was also the most accomplished singer among the original cast. He recorded a folk music album, Come All Ye Fair and Tender Ladies, during his Bonanza years, and several of his tracks appear on the show’s box set collections.
His patience with television finally paid off in 1979 when he landed the title role in Trapper John, M.D., a medical drama spun off from M*A*S*H. The show ran for seven seasons and earned Roberts an Emmy nomination in 1981. He also briefly reunited with Lorne Greene for a two-part episode of Vega$ in 1982. Roberts continued acting in guest roles through the 1990s and 2000s, but largely stepped back from the spotlight as he aged. He was also a committed civil rights activist who marched in Selma, Alabama, in the 1960s. Pernell Roberts died on January 24, 2010, at age 81, from pancreatic cancer.
Dan Blocker — Hoss Cartwright
Dan Blocker’s death remains one of the most heartbreaking chapters in television history. As Hoss Cartwright — the gentle, lovable giant of the Ponderosa — Blocker was arguably the most beloved member of the cast. Standing 6’4″ and weighing over 300 pounds, he brought a surprising tenderness and comic timing to a character that could easily have been a one-note brute.
Born in De Kalb, Texas, in 1928, Blocker was reportedly the largest baby ever delivered in Bowie County at the time, weighing 14 pounds at birth. Before acting, he served as an infantry sergeant in the Korean War and earned a master’s degree in dramatic arts. He appeared in all of Bonanza‘s first 13 seasons and became one of the most recognized faces on American television.
Outside the show, Blocker starred alongside Frank Sinatra in the 1963 comedy Come Blow Your Horn and returned for the 1968 Tony Rome sequel Lady in Cement. He also co-founded the Bonanza Steakhouse restaurant chain in 1963, appearing as Hoss in commercials and making personal appearances at franchise locations across the country. Director Robert Altman had planned to cast Blocker in The Long Goodbye, but that role never came to be.
On May 13, 1972, Dan Blocker died at age 43 from a pulmonary embolism — a blood clot that followed routine gallbladder surgery. His death devastated the cast and crew. The show’s fourteenth and final season opened with a somber tribute, and Hoss’s absence hung over every remaining episode. Bonanza was canceled the following year, and many involved with the show acknowledged that it simply couldn’t continue without him.
Michael Landon — Little Joe Cartwright
If any cast member went on to define an era of American television after Bonanza, it was Michael Landon. As Little Joe, the youngest and most hot-headed Cartwright son, Landon was the show’s heartthrob — but he was also quietly learning the craft of writing, directing, and producing behind the scenes.
Born Eugene Maurice Orowitz in Forest Hills, Queens, in 1936, Landon had already made a name for himself as a teenage werewolf — literally — in the 1957 horror film I Was a Teenage Werewolf before Bonanza made him a household name. He appeared in all 431 episodes and directed dozens more during the show’s run.
When Bonanza ended, Landon didn’t miss a beat. He created, produced, wrote, directed, and starred in Little House on the Prairie (1974–1983), playing Charles Ingalls in an adaptation of Laura Ingalls Wilder’s beloved books. The show became a massive hit and earned multiple Emmy and Golden Globe nominations. Landon maintained full creative control and remained the series’ executive producer even after it was retooled as Little House: A New Beginning in 1982.
He followed that success with Highway to Heaven (1984–1989), in which he played a probationary angel sent to Earth to help people in need. Landon was known for hiring his own children as part of the crew and for bringing real cancer patients and people with disabilities onto the set to ensure authenticity in the show’s storylines.
Landon was married three times and had nine children. In April 1991, he was diagnosed with pancreatic cancer that had already spread to his liver. He spoke publicly about his diagnosis, appearing on The Tonight Show with Johnny Carson in one of the most watched and emotionally charged interviews of the era. Michael Landon died on July 1, 1991, at age 54, at his home in Malibu, California. He left behind an extraordinary body of work — three long-running hit series, each one built on his vision of decency and family.
David Canary — Candy Canaday
David Canary joined Bonanza in 1967 as Candy Canaday, a ranch foreman who became a trusted member of the Cartwright inner circle. Though not part of the original cast, Canary appeared in over 90 episodes across two separate stints on the show (1967–1970 and 1972–1973) and became a fan favorite in his own right.
Born in Elwood, Indiana, in 1938, Canary was a gifted athlete who played football at the University of Cincinnati on a scholarship. He studied at the Cincinnati College-Conservatory of Music and trained seriously as an actor before transitioning to television. Before Bonanza, he appeared in Peyton Place and various other series.
After Bonanza ended, Canary found his greatest and most enduring success in daytime television. He joined the cast of All My Children in 1981, playing the dual roles of Adam and Stuart Chandler — twin brothers with wildly different personalities. His performance earned him five Daytime Emmy Awards for Outstanding Lead Actor, a record that stood for years. He remained on the soap opera, with occasional breaks, until 2010.
Canary was also a trained singer and musician, and he brought those talents to both Bonanza and his stage work. He continued acting in regional theater productions throughout his career. David Canary died on November 16, 2015, at age 77, from natural causes at his home in Wilton, Connecticut. His All My Children co-stars and Bonanza fans alike mourned the loss of one of the most versatile actors to grace both daytime and primetime television.
Mitch Vogel — Jamie Hunter Cartwright
Mitch Vogel was the youngest member of the Bonanza cast, joining the show in 1970 at just 14 years old. He played Jamie Hunter, an orphan boy taken in by the Cartwrights, and appeared in the show’s final three seasons. It was a significant role for a teenager — stepping into a family unit that millions of viewers had watched for over a decade.
Born in 1956, Vogel had already appeared in several films before Bonanza, including the 1969 movie The Reivers alongside Steve McQueen. After the show ended in 1973, he guest-starred in several other series, including Gunsmoke, The Virginian, and a brief stint on Michael Landon’s Little House on the Prairie in 1974–1975.
By 1978, Vogel had retired from acting entirely. He formed a rock band, moved to Pittsburgh, and eventually settled in Southern California after getting married in 1985. He and his wife raised two daughters far from the entertainment industry. In 2002, he returned to the Ponderosa filming locations for a Travel Channel special, TV Road Trip, narrating memories of his time on the show. He also participated in the 2005 Bonanza Convention and the 2010 Bonanza Weekend in Liverpool, England. Of all the main and recurring cast members, Vogel remains one of the few surviving links to the series.
Frequently Asked Questions
Are any of the original Bonanza cast members still alive?
No. All four original Cartwright family actors — Lorne Greene, Pernell Roberts, Dan Blocker, and Michael Landon — have passed away. Dan Blocker was the first to die in 1972, followed by Greene in 1987, Landon in 1991, and Roberts in 2010. Some recurring and guest cast members, including Mitch Vogel (Jamie Hunter), are still living.
Why was Bonanza canceled?
The show’s cancellation in 1973 was largely tied to the death of Dan Blocker (Hoss) in May 1972. Blocker died from a pulmonary embolism after gallbladder surgery at age 43. The producers attempted to continue without him for a fourteenth season, but ratings dropped and the creative heart of the show had been fundamentally damaged. NBC pulled the plug after that final season.
How many episodes of Bonanza were made?
Bonanza ran for 14 seasons and produced 431 episodes between September 1959 and January 1973. It was the second-longest-running western in U.S. television history, behind only Gunsmoke, which ran for 20 seasons. At its peak, Bonanza was the number-one rated show in America for three straight years.
What other shows did Michael Landon create after Bonanza?
Michael Landon went on to create, write, direct, and star in two more long-running hit series: Little House on the Prairie (1974–1983) and Highway to Heaven (1984–1989). Both shows reflected Landon’s interest in family-oriented storytelling and moral themes. He remained one of the most prolific and successful figures in television until his death from pancreatic cancer in 1991 at age 54.
