For nine nostalgic seasons in the 1970s and early '80s, viewers tuned in by the millions to watch "Little House on the Prairie," the series based on the famous autobiographical books by Laura Ingalls Wilder. Starring Melissa Gilbert as Laura Ingalls, "Little House" was equal parts heartwarming and heartbreaking. Over the years, the fictional family coped with the struggles of 19th-century pioneer life: crops lost to harsh weather; fires destroying livelihoods; illnesses and injuries with limited medical resources. Though many of the plot points veered from the original material, the show kept certain true-life details about Laura, such as her marriage to Almanzo Wilder, the death of her newborn son and the birth of daughter Rose, and her interest in writing a book about her childhood. In the years after the show wrapped, the cast reunited for three TV-movie sequels. The franchise literally ended with a bang: In "Little House: The Last Farewell," the residents of Walnut Grove blow up nearly all of the buildings in protest over the town's takeover by a railroad tycoon. 

For the most part, the show's cast got along well, and members have reunited over the years for various fan appearances and charity events. Yet while "Little House" remains a fond memory and a career springboard, the lives of the actors haven't always been as bright as a prairie sun. Traumas, illnesses, and other personal struggles continued even when the cameras stopped rolling. Here's a look at some of those hardships; you might come away with an even greater appreciation for the residents of Walnut Grove.

Already a bonafide star thanks to "Bonanza," Michael Landon was instrumental in shaping the direction of "Little House on the Prairie" as producer, director, and writer. Three of Landon's nine kids even appeared on the show; daughter Leslie Landon Matthews played several parts over the years, including Etta Plum, the teacher who replaces Laura in Season 9. Following the series finale, Landon went on to create and star in another heartwarming drama, "Highway to Heaven." 

Tragically, Landon's own earthly life was far too brief. In April 1991, he was diagnosed with pancreatic cancer. Despite his vow to fight, Landon died just three months later. In November 2025, Melissa Gilbert and Dean Butler (Almanzo Wilder) joined the Pancreatic Cancer Action Network to promote awareness of the disease which took their beloved castmate. On Instagram, Gilbert wrote, "Michael wasn't just my co-star. He was my mentor, my friend and the closest thing to family I've ever had. ...I carry his courage and love with me every day, and it drives me to fight for others affected by this disease." Butler added, "Michael Landon left us 34 years ago, yet his spirit lives on in every Little House story of love, family, and community."

Onscreen, Karen Grassle was Caroline Ingalls, the wise mother and loyal wife who eventually helped the Oleson family run a restaurant. It's hard to picture the virtuous "Ma" touching so much as a drop of liquor, but in real life, Grassle struggled with alcohol addiction. In her autobiography "Prairie Dust: Reflections on Life, Love, and Loss from 'Little House's' Ma," the actress recalls arriving to the set looking a wreck and relying on her hair and makeup team to restore her to the fresh-faced pioneer mom aesthetic. At one point, she got so drunk on a plane that she made out with a total stranger and went to his place after the flight. "I don't know what the public would have thought of Caroline Ingalls behaving like that," she wrote (via New York Post). "Maybe they would have turned against me."

The California native finally got sober in 1977 after realizing her dependence was tied to her need for a happy family life. "I didn't have a clue that I wanted what Caroline Ingalls actually had," she recalled. This was a turning point for Grassle in other ways as well: She got the salary bump she'd long been fighting for, and she also began to make peace with costar Michael Landon, who she claims made sexist remarks and fought against her pay raise. "I am very grateful that we mended our fences," Grassle wrote. 

Behind her famous cheery smile as Laura Ingalls, Melissa Gilbert was living a tragic real-life story. Her parents divorced when she was only six years old, and her father, comedian Paul Gilbert, died by suicide five years later — a fact she only learned as an adult. "I still sometimes wonder why I wasn't good enough to stick around for," Gilbert confessed to Oprah Winfrey in 2014 (via YouTube). The actress's high-profile relationships included one with Rob Lowe, by whom she became pregnant. Not long after the couple broke up, Gilbert suffered a miscarriage. In her memoir "Prairie Tale," she wrote, "I had lost my baby and my relationship with Rob, and it hurt like hell."

Gilbert's troubles didn't end there. She battled addiction to prescription drugs and alcohol, at one point consuming two bottles of wine daily. Her first two marriages ended in divorce. Getting sober in 2004 helped bring her personal life into alignment, but she continued to struggle with health issues, in particular neck and spinal damage exacerbated by a fall she took as a contestant on "Dancing With the Stars" in 2012. Her hopes of running for Congress in Michigan in 2016 were dashed when doctors told her she needed further surgery. For years, Gilbert also experienced an unusual rage-evoking aversion to certain noises such as chewing gum. Only recently did she discover she has a neurological condition called misophonia, which she learned to manage through behavioral therapy at Duke University. Today, TV's "Half-Pint" is enjoying better health and a loving marriage to actor Timothy Busfield, whom she wed in 2013.

Of all the characters in "Little House," oldest daughter Mary Ingalls perhaps broke the most viewers' hearts. As played by Melissa Sue Anderson, Mary went blind from scarlet fever in Season 4, an acting challenge which earned Anderson an Emmy nomination. The character also suffered two horrible losses: first when she miscarried her first child with husband Adam, and again when her second child died in a fire accidentally set by her adopted brother. Following the series run, Anderson went on to a long string of featured roles in other shows and TV movies. In 1990, she married Michael Sloan, a writer and producer whom she'd met during a guest shot on "The New Alfred Hitchcock Presents." They had two children, Piper and Griffin. 

In August 2025, Anderson experienced her own personal heartbreak when Sloan died at age 78. His online obituary reported that he "passed away peacefully," and that he would be remembered as a loving husband and father who was also devoted to the family dogs. At this writing, Anderson had not released a personal statement, but fans are wishing her comfort as she works through her grief. 

During its nine-season run, "Little House on the Prairie" was graced with a host of talented actors in various featured and cameo roles. Sadly, many of them have passed away in the years following the series finale, and some well before their time. Among them is Victor French (seen at right), who played the Ingalls' neighbor and good friend Isaiah Edwards. The friendship between French and Michael Landon continued with their next project together, "Highway to Heaven," in which they co-starred as an ex-cop and an angel sent from heaven who join forces to help ordinary folks with their earthly problems. French died of lung cancer in 1989 — just two years before Landon's passing — at just 54 years of age.

"Little House" helped launch the career of Shannen Doherty, who appeared in 18 episodes as Jenny Wilder, Almanzo Wilder's niece who came to live with him and Laura. Following the series' run, Doherty went on to legit stardom with her signature roles in "Heathers," "Beverly Hills, 90210," and "Charmed." But offscreen, the actress's party-girl ways and reported feuds with castmates stigmatized her, and her fraught love life included three marriages which ended in divorce. In 2015, at just 43, Doherty was diagnosed with breast cancer. Treatment brought her into remission for a few years, but it eventually returned and metastasized to other areas of her body. She died in July 2024 at age 53. 

Other featured "Little House" players who are no longer with us include Katherine MacGregor, who played the snooty Harriet Oleson; Dobbs Greer, the town's beloved Reverend Alden; Kevin Hagen, the trusted Doc Baker; Merlin Olsen and Hersha Parady, the Ingalls' good friends the Garveys; and Richard Bull, the patriarch Nels Oleson.
