Beate Sirota Gordon (1923-2012) was an Austrian-born American. In 1946, at age 22, she was responsible for the inclusion of women's rights into the Japanese constitution. To protect that work, she remained silent about her contributions for much of her life.Naming citation (MPC batch dated 2019-12-12), IAU / Minor Planet Center, via NASA/JPL
