Bettie Page, the 1950s secretary-turned-model whose controverisal photographs in skimpy attire or none at all helped set the stage for the 1960s sexual revolution, died Thursday. She was 85.

Page suffered a heart attack last week in Los Angeles and never regained consciousness, said her agent, Mark Roesler. Before the heart attack, Page had been hospitalized for three weeks with pneumonia.

"She captured the imagination of a generation of men and women with her free spirit and unabashed sensuality," Roesler said. "She is the embodiment of beauty."

Page, who was also known as Betty, attracted national attention with magazine photographs of her sensuous figure in bikinis and see-through lingerie that were quickly tacked up on walls in military barracks, garages and elsewhere, where they remained for years.

Her photos included a centerfold in the January 1955 issue of then-fledgling Playboy magazine, as well as controversial sadomasochistic poses.

"I think that she was a remarkable lady, an iconic figure in pop culture who influenced sexuality, taste in fashion, someone who had a tremendous impact on our society," Playboy founder Hugh Hefner told The Associated Press on Thursday. "She was a very dear person."

Page mysteriously disappeared from the public eye for decades, during which time she battled mental illness and became a born-again Christian.

After resurfacing in the 1990s, she occasionally granted interviews but refused to allow her picture to be taken.

"I don't want to be photographed in my old age," she told an interviewer in 1998. "I feel the same way with old movie stars. ... It makes me sad. We want to remember them when they were young."

The 21st century indeed had people remembering her just as she was. She became the subject of songs, biographies, Web sites, comic books, movies and documentaries. A new generation of fans bought thousands of copies of her photos, and some feminists hailed her as a pioneer of women's liberation.

Gretchen Mol portrayed her in 2005's "The Notorious Bettie Page" and Paige Richards had the role in 2004's "Bettie Page: Dark Angel." Page herself took part in the 1998 documentary "Betty Page: Pinup Queen."

Hefner said he last saw Page when he held a screening of "The Notorious Bettie Page" at the Playboy Mansion. He said she objected to the fact that the film referred to her as "notorious," but "we explained to her that it referred to the troubled times she had and was a good way to sell a movie."
