Number 51

On the centenary of gifted, careful researcher Rosalind Franklin, a reminder of the obstacles she overcame.

[James] Watson and his Cambridge collaborator and eventual fellow Nobel Laureate Francis Crick were not doing laboratory research on the structure of DNA, but they were actively attempting to build a model of it. Franklin’s image provided them with a breakthrough. Franklin was a cautious scientist, believing that modeling should await airtight scientific evidence. But Watson and Crick were less hesitant and became convinced that their double helix model must be correct.
