In April, National Geographic News published a story about the letter in which scientist Francis Crick described DNA to his 12-year-old son. In 1962, Crick was awarded a Nobel Prize for discovering the structure of DNA, along with fellow scientists James Watson and Maurice Wilkins. Several people posted comments about our story that noted one name was missing from the Nobel roster: Rosalind Franklin, a British biophysicist who also studied DNA. Her data were critical to Crick and Watson's work, but as several commenters noted, Franklin was robbed of recognition. (See her section below for details.)

She was not the first woman to have endured indignities in the male-dominated world of science, but Franklin's case is especially egregious, said Ruth Lewin Sime, a retired chemistry professor at Sacramento City College who has written on women in science. Over the centuries, female researchers have had to work as "volunteer" faculty members, seen credit for significant discoveries they've made assigned to male colleagues, and been written out of textbooks.
