Geraldine Doyle, 86, who as a 17-year-old factory worker became the inspiration for a popular World War II recruitment poster that evoked female power and independence under the slogan "We Can Do It!," died Dec. 26 at a hospice in Lansing, Mich.

Her daughter, Stephanie Gregg, said the cause of death was complications from severe arthritis.

For millions of Americans throughout the decades since World War II, the stunning brunette in the red and white polka-dot bandanna was Rosie the Riveter.

Rosie's rolled-up sleeves and flexed right arm came to represent the newfound strength of the 18 million women who worked during the war and later made her a figure of the feminist movement.

But the woman in the patriotic poster was never named Rosie, nor was she a riveter. All along it was Mrs. Doyle, who after graduating from high school in Ann Arbor, Mich., took a job at a metal factory, her family said.

One day, a photographer representing the United Press came to her factory and captured Mrs. Doyle leaning over a piece of machinery and wearing a red and white polka-dot bandanna over her hair.

In early 1942, the Westinghouse Corp. commissioned artist J. Howard Miller to produce several morale-boosting posters to be displayed inside its buildings. The project was funded by the government as a way to motivate workers and perhaps recruit new ones for the war effort.

Smitten with the United Press photo, Miller reportedly was said to have decided to base one of his posters on the anonymous, slender metal worker - Mrs. Doyle.

For four decades, this fact escaped Mrs. Doyle, who shortly after the photo was taken left her job at the factory. She barely lasted two weeks.

A cellist, Mrs. Doyle was horrified to learn that a previous worker at the factory had badly injured her hands working at the machines. She found safer employment at a soda fountain and bookshop in Ann Arbor, where she wooed a young dental school student and later became his wife.

In 1984, Mrs. Doyle and her family came across an article in Modern Maturity magazine, a former AARP publication, that connected her UPI photo with Miller's wartime poster.
