Nina Einhorn née Rajmic (1925–2002) was a Jewish Polish-born Swedish physician who conducted research in the field of gynaecological oncology. A survivor from the Warsaw Ghetto, she studied medicine in Warsaw, met her husband-to-be, the physician Jerzy Einhorn, and emigrated to Sweden in the late 1940s. In 1964, she was engaged by the Radiumhemmet cancer treatment centre which she headed from 1986. Specializing in research into ovarian cancer, she chaired both the Swedish Ovarian Cancer Study Group and the International Gynecological Cancer Society. Einhorn also supported the Jewish cause, chairing for a time the Israeli institution Keren Hayesod. After she was diagnosed with breast cancer in 1999, she continued to conduct research until her death in May 2002.[1][2][3]
