A tribute to scientist Rosalind Franklin and her crucial contribution to the discovery of the structure of DNA. Front and centre is a motif inspired by the famous Photo 51, the X-ray diffraction image that was pivotal to the discovery that DNA is a double helix. The double helix itself adorns the back and sole of the sock.
