in 1947. He has been credited as being the first person to demonstrate that the DNA molecule was
probably helical in shape. Maurice Wilkins wrote in his autobiography (page
160) that he asked Stokes to predict what a helical structure
would look like as an x-ray diffraction photograph, and that he was able to
determine this by the next day through mathematical calculations made during a
short train journey. Stokes continued to work on optical diffraction in large
biological molecules. His publications include the books
The Theory of the Optical Properties of Inhomogeneous Materials.
