(CBS News)-- Bonnie Franklin, the pert, redheaded U.S. actress whom millions came to identify with for her role as divorced mom Ann Romano on the long-running sitcom "One Day at a Time," has died.
She died Friday at her home due to complications from pancreatic cancer, family members said. She was 69. Her family had announced she was diagnosed with cancer in September.
Franklin was a veteran stage and television performer before "One Day At a Time" made her a star. The series was groundbreaking for its focus on a young divorced mother seeking independence from a suffocating marriage. It premiered on CBS in December 1975, just five years after the network had balked at having Mary Tyler Moore play a divorcee on her own comedy series.
Ann Romano was raising two teenage girls (played by Mackenzie Phillips, already famous for the film "American Graffiti," and a previously unknown Valerie Bertinelli). "One Day At a Time" ran on CBS until 1984, by which time both daughters had grown and married, while Romano had remarried and become a grandmother. During the first seven of its nine seasons on the air, the show was a Top 20 hit.
"One Day at a Time" dealt with contemporary issues once absent from TV comedies such as premarital sex, birth control, suicide and sexual harassment - issues that had previously been overlooked by TV comedies whose households were usually headed by a husband and wife or, rarely, a widowed parent.
"I think a lot of things resonated with people," Phillips told CBSNews.com about the series last year. "I think having two sisters who are so diametrically opposed with a parent that was into having these girls grow up in such a specific way. Being a single parent...Julie being a rebel...Barb, Valerie -- being the one who wanted to please Mom all the time, and those roles would switch. Just like real life. Just like a real family."
Meanwhile, the series weathered its own crises as Phillips was twice written out of the series to deal with her drug abuse and other personal problems.
Writing in her 2009 memoir "High On Arrival," Phillips remembered Franklin as hardworking and professional, even a perfectionist.
"Bonnie felt a responsibility to the character and always gave a million notes on the scripts," Phillips wrote. "Above all, she didn't want it to be sitcom fluff - she wanted it to deal honestly with the struggles and truths of raising two teenagers as a single mother."
In her 2008 memoir "Losing It," Bertinelli noted that Franklin, just 31 when the show began, wasn't old enough to be her real mother.
Even so, wrote Bertinelli, "within a few days I recognized her immense talent and felt privileged to work with her. ... She was like a hip, younger complement to my real mom."
The truth of "One Day at a Time" was brought home to Franklin when in 2005 she got together with both TV daughters for a "One Day at a Time" reunion special. She told both actresses, "You are living, in a sense, Ann Romano's life -- you are single parents raising teenage kids. That is shocking and terrifying to me."
Franklin herself was married for 29 years. Her husband, TV producer Marvin Minoff, died in 2009.
Born Bonnie Gail Franklin in California, she entered show business at an early age. She was a child tap dancer and actress, and a protege of Donald O'Connor, with whom she performed in the 1950s on NBC's "Colgate Comedy Hour."
A decade later, she was appearing on such episodic programs as "Mr. Novak," ''Gidget" and "The Man from U.N.C.L.E."
On stage, Franklin was in the original Broadway production of "Applause," for which she received a 1970 Tony Award nomination, and other plays including "Dames at Sea" and "A Thousand Clowns."
Franklin's recent credits include appearances on "The Young and the Restless" and the TV Land comedy "Hot in Cleveland," which again reunited her with Bertinelli, one of that show's regulars.
Last year, Franklin reunited with the "One Day at a Time" cast at the TV Land Awards.
