Frantz Aranka was a gymnast of BBTE. In 1928, she took part at the Amsterdam Olympics, where, for the first time, women could also compete in gymnastics. As a member of the Hungarian team, she finished fourth.
The Hungarian women’s team led after the first day, but fell back to fourth on the second day. In November 1932, the board of directors of the Association of Hungarian Gymnastics Associations (MOTESZ) donated a large bronze medal to the members of the gymnastics team, with five ringed enamels and the engraved inscription “In memory and compensation - 1928”.
Retiring from active sports, she became a coach and sports diplomat. In 1948 she was elected to the Women’s Gymnastics Technical Committee of the International Gymnastics Association (FIG), where she first represented Hungarian gymnastics as a member (1948-1972) and then as the head of the committee. The multilingual sports diplomat participated in a total of 11 Olympics.
