Olympic champion Mary Lou Retton in intensive care as she fights rare form of pneumonia

Olympic champion American gymnast Mary Lou Retton, 55, has been in the hospital more than a week fighting a "very rare form of pneumonia," according to according to a fundraising post from her daughter, McKenna Kelley.

"My amazing mom, Mary Lou,... is fighting for her life," wrote Kelley. "She is not able to breathe on her own. She’s been in the [intensive care unit] for over a week now. Out of respect for her and her privacy, I will not disclose all details. However, I will disclose that she not insured."

The fundraiser has collected more than $150,000 for the U.S. gymnastics legend, far surpassing the original $50,000 goal.

Retton struck gold at the 1984 Olympic Games in Los Angeles, becoming the first American woman to claim all-around gold at the Games as her perfect 10.0 vault sealed the title over Romania’s Ecaterina Szabo and captivated the home audience.

In LA, she claimed five medals in total including team and vault silver and uneven bars and floor exercise bronze, in addition to her all-around triumph.

It would be 20 years until another American woman, Carly Patterson, claimed the Olympic all-around title. Since Patterson, the U.S. has dominated the event with Nastia Liukin, Gabby Douglas, Simone Biles and Sunisa Lee cliching subsequent golds.

Though she retired in 1986, Retton continued to be one of the sport’s biggest names, especially in the United States. She served as an analyst for NBC during its coverage of the 1988 Olympic Games in Seoul.

In 1997, she was inducted into the International Gymnastics Hall of Fame.
