Rosalind Franklin
The Nobel Prize for finding the structure of the DNA molecule was shared by three men in 1962. But it was a woman, Rosalind Franklin, who made that discovery possible. Working with Maurice Wilkins, Franklin used the technique known as X-ray crystallography to show that the DNA had a helical, or spiral, shape. Her results gave James Watson and Francis Crick the key insight that led them to conclude in 1953 that the DNA molecule was shaped like a double helix. That breakthrough enabled scientists to deduce how genes are passed by heredity. Because female scientists in the early 1950s were often forced to work in the shadow of their male counterparts, Franklin¡¯s pivotal work has been relegated to a footnote to science history.
