Walking into the lab and seeing this double helix, of course, it looked familiar because all of the stator of the dimensions was the stuff that we got from our X-ray diffraction patterns.

So, it looked right and it was sheer elegance. My name is Melinda Baldwin. The Franklin and Gosling paper was primarily about crystallographic work. Page , Rosalind E. Franklin and R. At the time, X-ray crystallography of large molecules — the sort of molecules that you get in living bodies — was still a very, very small field.

It had really started in the s. Everybody was interested in the structure of proteins back in the 30s because nobody thought that DNA could possibly be complicated enough to be the molecule of life.

What you need is an X-ray source, which in those days would have been an X-ray tube. I needed lots of fibres. Sodium thymonucleate fibres give two distinct types of X-ray diagram.

The Secret of Life is a story of genius and perseverance, but also a saga of cronyism, misogyny, anti-Semitism, and misconduct. A vibrant evocation of Cambridge in the s, Markel also provides colorful depictions of Watson and Crick—their competitiveness, idiosyncrasies, and youthful immaturity—and compelling portraits of Wilkins, Pauling, and most cogently, Rosalind Franklin. The Secret of Life is a lively and sweeping narrative of this landmark discovery, one that finally gives the woman at the center of this drama her due.
