Rosalind Franklin (25 July 1920 – 16 April 1958) - Basically, she discovered DNA and then men took credit for the idea. From Wikipedia: She recorded a photograph of a DNA molecule that another researcher at King's College, Maurice Wilkins, showed to James Watson and Francis Crick without her knowledge or permission. This image helped Watson and Crick construct a model of DNA ... Wilkins, Crick and Watson were awarded a Nobel Prize jointly, some years later, after Franklin's death. Hostility between Franklin and her colleagues is a matter of record. There has been extensive comment in biographical works and other publications that her work did not bring adequate recognition during her lifetime.
