Meet the real Rosie the Riveter, who was unknown until a yearslong investigation revealed her identity

Before the war, women were in traditionally "female" fields such as nursing and teaching.

Following the attack on Pearl Harbor, women joined the armed forces at remarkable rates. By 1943, over 310,000 women were employed in the US aircraft industry, comprising 65% of the industry's workforce, a stark contrast to the mere 1% representation before the outbreak of war, per the Defense Logistics Agency.

Forbes reported that between 1940 and 1945, female participation in the US workforce increased from 27% to nearly 37%. By 1945, a quarter of married women worked in jobs outside the home.

One photo, taken in 1942 by a photographer touring the Naval Air Station to show what life was like for women working in the aircraft industry, appeared to catch the attention of a Pittsburgh artist named J. Howard Miller.

The New York Times reported that Miller created a 1943 poster for the Westinghouse Electric Corporation that became one of the most iconic images in history.

The image featured a "Rosie," as female factory workers were known at the time, flexing her bicep, wearing a red polka-dot bandana and a riveter's uniform. Above her were the inspiring words "We Can Do It!"

The woman in Miller's poster soon came to be known as "Rosie the Riveter" after musicians Redd Evans and John Jacob Loeb released a popular song with the same title in 1943.

The New York Times reported that the poster was initially only displayed in the Westinghouse Electric Corporation plant to deter women from not showing up to work and strikes among female workers.

However, once the poster was published and gained national exposure in the early 1980s, it evolved into an emblem of the feminist movement and emerged as one of the most iconic images in pop culture.

Geraldine Hoff Doyle, who worked in a Navy plant in Michigan, was long considered to be the inspiration behind the iconic image.

The New York Times reported that Doyle came forward in the 1980s and claimed to be the woman in a photo believed to have inspired Miller's famous poster.

Doyle had seen the photo, which was published without its original caption and the correct names of the women in the photograph.

She mistakenly identified herself as the woman in the photo, and since she bore a striking resemblance to the woman, she was widely accepted as the real-life Rosie the Riveter.

In 2009, during a reunion of war-era Rosies, 88-year-old Naomi Parker Fraley (pictured) attended a reunion of war-era Rosies, where she spied a photo of herself working at the Naval Air Station in Alameda, California, in a historical display — and saw another woman's name listed underneath the image as the inspiration for Miller's famous "We Can Do It!" poster.

The photo in question showed a then-20-year-old Naomi Parker Fraley wearing a red-and-white-polka-dot bandana and working on a turret lathe.

"I couldn't believe it because it was me in the photo, but there was somebody else's name in the caption: Geraldine," Parker Fraley told People in 2016. "I was amazed."

People reported that Parker Fraley contacted the World War II Home Front National Historical Park with her saved newspaper clipping, which included the original caption that listed her as the woman in the photo. 

"I just wanted my own identity," she said. "I didn't want fame or fortune, but I did want my own identity."

However, Parker Fraley, then 95, would not be able to correct the record for another six years. In 2015, she was approached by Seton Hall University professor James J. Kimble, who had been on a quest to discover Rosie the Riveter's true identity for six years.

After Parker Fraley showed Kimble the evidence that she had been Miller's inspiration, he published an article in an academic journal, "Rosie's Secret Identity," in 2016. People then published a feature about the discovery, and Parker Fraley was finally recognized by the media at large as the inspiration behind Rosie the Riveter. 

"She had been robbed of her part of history," Kimble told People. "It's so hurtful to be misidentified like that. It's like the train has left the station and you're standing there and there's nothing you can do because you're 95 and no one listens to your story."

Parker Fraley told People that after she was identified as the inspiration for Rosie the Riveter, she began receiving fan mail.

Miller's illustration of Rosie the Riveter has come to embody the tenacity and strength of women.

"The women of this country these days need some icons," Parker Fraley told People. "If they think I'm one, I'm happy about that."

Naomi Parker Fraley died on January 20, 2018, at the age of 96.
