A native of Winnebago, Illinois, Hattie was one of nine children born to Walter and Hattie LaTour Peterson, of Scandinavian ancestry.[2]
She joined the All American League with the Rockford Peaches club, where she spent two seasons from 1948 to 1949.[2] She was forced to retire after injuring her throwing arm.[1] Afterwards, she moved with her family to Phoenix, Arizona.[2]
Hattie returned to Rockford, Illinois in 2007, where she lived most of her life. In her spare time, she enjoyed playing the accordion; a hobby that she did not pick up until she was in her 40s. As a result, she was still active in accordion clubs and entertained fellow retirement home residents.[2]
In 1988, Hattie A. Peterson Oberg received further recognition when she became part of Women in Baseball, a permanent display based at the Baseball Hall of Fame and Museum in Cooperstown, New York, which was unveiled to honor the entire All-American Girls Professional Baseball League.[3]
