Gretchen Hehenberger
Gretchen Hehenberger was an Austrian gymnast who competed in the 1948 Summer Olympics.
Before moving to Austria after her marriage to Ernst Hehenberger in 1943, Gretchen Sievers twice won the German championships in a combined Gymnastics and Track & Field competition including 10 different disciplines. She barely missed the 1936 Olympics due to a broken leg. In 1948, she already was the mother of two boys, Rainer and Michael, respectively.
