Four years later, she set out to find other American women who were juggling Olympic training with diaper changes, bath times and breast-feeding.
(For more on why this is such a big deal, check out Petula Dvorak's great article in the Washington Post.)
Pottheiser photographed eight of this year's Olympians in a combination of formal portraits and documentary images. A commercial photographer who mainly works with male athletes, she said photographing the women was a humbling and eye-opening experience.
"It was remarkable to me how relaxed they were. They recognized that when they step off the court or the field, there's a 3-year-old that wants to go to the park and doesn't care whether you had a bad game."
She was also surprised by how normal they seemed, despite demanding training schedules.
"Candace Parker was out walking her dogs at 7:30 a.m. and picking up poop just like everyone else. It's not the image you have of glorified athletes – they are just normal people who are the best in the world at what they do."
Pottheiser now has a newly vested interest in watching the London Games.
"I was watching Lashinda Demus last night, and I said, 'That's my mom, that's my mom!' I think that all of them are supermoms, and to see them in action was remarkable."
