Betty White, who had the longest running career for any woman in TV, died Friday, People and the Washington Post reported, quoting her agent. She was 99. 

“Even though Betty was about to be 100, I thought she would live forever. I will miss her terribly and so will the animal world that she loved so much. I don’t think Betty ever feared passing because she always wanted to be with her most beloved husband Allen Ludden. She believed she would be with him again,” her agent and close friend Jeff Witjas told PEOPLE in a statement on Friday.

White was to celebrate her 100th birthday on January 17. 

White was gearing up to celebrate her 100th birthday on January 17. Ahead of her centennial year, she opened up to PEOPLE about how she was feeling about turning 100 years old.

“I’m so lucky to be in such good health and feel so good at this age,” said the veteran actress. “It’s amazing.”

According to White, being “born a cockeyed optimist” was the key to her upbeat nature. “I got it from my mom, and that never changed,” she said. “I always find the positive.”

Of course, the iconic actress also cracked a joke about the secret to her long life, telling PEOPLE: “I try to avoid anything green. I think it’s working.”

White was famous for playing Rose Nylund in ‘The Golden Girls’ from 1985 to 1992. Her career lasted for eight decades.

Betty played roles in “Life with Elizabeth,” “Date with the Angels,” “The Love Boat,” “Mama’s Family,” “The Golden Palace,” “Ladies Man,” “That ’70s Show,” “Higglytown Heroes,” “Boston Legal,” “The Bold and the Beautiful,” “Pound Puppies,” “Hot in Cleveland,”. 

Such was her popularity that even White’s birthday became a national event: In January 2012, NBC aired “Betty White’s 90th Birthday Party” as a star-studded prime-time special. She would later appear in such series as “Bones” and Fireside Chat With Esther” and in 2019 gave voice to one of the toys, “Bitey White,” in “Toy Story 4.”

White remained youthful in part through her skill at playing bawdy or naughty while radiating niceness. The horror spoof “Lake Placid” and the comedy “The Proposal” were marked by her characters’ surprisingly salty language. And her character Catherine Piper killed a man with a skillet on “Boston Legal.”

But she almost wasn’t cast as “Happy Homemaker” Sue Ann Nivens in “The Mary Tyler Moore Show” in 1973. She and her husband, Allen Ludden, were close friends of Moore and Moore’s then-husband, producer Grant Tinker. It was feared that if White failed on the show, which already was a huge hit, it would be embarrassing for all four. But CBS casting head Ethel Winant declared White the logical choice. Originally planned as a one-shot appearance, the role of Sue Ann (which humorously foreshadowed Martha Stewart) lasted until Moore ended the series in 1977.

“While she’s icky-sweet on her cooking show, Sue is really a piranha type,” White once said. The role brought her two Emmys as supporting actress in a comedy series.

In 1985, White starred on NBC with Bea Arthur, Rue McClanahan and Estelle Getty in “The Golden Girls.” Its cast of mature actresses, playing single women in Miami retirement, presented a gamble in a youth-conscious industry. But it proved a solid hit and lasted until 1992.

White played Rose, a gentle, dim widow who managed to misinterpret most situations. She drove her roommates crazy with off-the-wall tales of childhood in fictional St. Olaf, Minnesota, an off-kilter version of Lake Wobegon.

The role won her another Emmy, and she reprised it in a short-lived spinoff, “The Golden Palace.”

She also appeared in numerous miniseries and TV movies and made her film debut as a female U.S. senator in Otto Preminger’s 1962 Capitol Hill drama “Advise and Consent.”

White began her television career as $50-a-week sidekick to a local Los Angeles TV personality in 1949. She was hired for a local daytime show starring Al Jarvis, the best-known disc jockey in Los Angeles.

It was then she got a tip to start lying about her age.

“We are so age-conscious in this country,” she said in a 2011 interview with The Associated Press. “It’s silly, but that’s the way we are. So I was told, ‘Knock four years off right now. You’ll be blessing yourself down the road.’

“I was born in 1922. So I thought, ‘I must always remember that I was born in 1926.’ But then I would have to do the math. Finally, I decided to heck with it.”

White proved to be a natural for the new medium. She was bright, pretty and likable, with a dimpled, eye-crinkling smile. A 1951 Los Angeles Times headline said: “Betty White Hailed as TV’s Busiest Gal.”

“I did that show 5½ hours a day, six days a week, for 4½ years,” she recalled in 1975. Jarvis was replaced by actor Eddie Albert, and when he went to Europe for the film “Roman Holiday,” she headed the show.

A sketch she had done with Jarvis turned into a syndicated series, “Life With Elizabeth,” which won her first Emmy. For a time she did interviews on “The Betty White Show” in the daytime, filmed the series at night and often turned up on a late-night talk show. She also appeared on commercials and every New Year’s narrated the Pasadena Rose Parade.

With the glib tongue and quick responses nurtured in the Jarvis years, she was a welcome guest on “I’ve Got a Secret,” “To Tell the Truth,” “What’s My Line” and other game shows — all the way up to the 2008 “Million Dollar Password,” which revived the game once hosted by Ludden, whom she had met when a contestant on his original “Password.”

That was in 1961, and the next year, while touring in summer theater during television’s off season, she starred with Ludden — by then a widower with three children — in the comedy “Critic’s Choice.”

White, who had claimed to be “militantly single” since a 1947-1949 marriage, weakened in her resolve.

“I had always said on `The Tonight Show’ and everywhere else that I would never get married again,” she told a reporter in 1963. “But Allen outnumbered me. He started in and even the children got in the act. And I surrendered — willingly.”

The marriage lasted from 1963 until his death from cancer in 1981.

Off-screen, White tirelessly raised money for animal causes such as the Morris Animal Foundation and the Los Angeles Zoo. In 1970-1971, she wrote, produced and hosted a syndicated TV show, “The Pet Set,” to which celebrities brought their dogs and cats. She wrote a 1983 book titled “Betty White’s Pet Love: How Pets Take Care of Us,” and, in 2011, published “Betty & Friends: My Life at the Zoo.”

Her devotion to pets was such that she declined a plum role in the hit 1997 movie “As Good As It Gets.” She objected to a scene in which Jack Nicholson drops a small dog down a laundry chute.
