Naomi Parker Fraley, the Californian waitress better known for her modelling work as Rosie the Riveter, has died at age 96 in Washington.
Ms Fraley is believed to have inspired the iconic World War II "We Can Do It" poster.
Her connection with the feminist character was only revealed in 2016 - 70 years after the poster was created - when she was tracked down by researcher Professor James J Kimble.
His six-year search for the real Rosie ruled out several other women who had claimed to be the inspiration for the character, according to the New York Times.
"I didn't want fame or fortune," Fraley told People magazine in 2016. "But I did want my own identity."
Rosie the Riveter represented the women who took over men's work during the war, filling factories and shipyards. She was a symbol of feminism and women's economic power.
