|Fortieth Anniversary at King's College London of the discovery of the structure of DNA in 1993. Pictured are four of the five names commemorated in the grey plaque on the background wall ( from left-right they are: Raymond Gosling, Herbert Wilson, Maurice Wilkins and Alexander Stokes)|
On the unveiling of the grey plaque to commemorate the fortieth anniversary of the discovery of the Double Helix at King's College London, Maurice Wilkins said these words:
Raymond Gosling (born 1926):
Alexander Stokes (1919-2003):

Herbert Wilson (1929-2008):
Though Herbert Wilson arrived six months before Watson and Crick unveiled the double helix to the world, his work with Maurice Wilkins uncovered essential information regarding the structure of DNA. Wilson arrived at the biophysics unit in September 1952 under tenure of the University of Wales. He soon began X-ray diffraction studies of DNA, nucleoproteins and cell nuclei under the guidance of Maurice Wilkins. The two collaborated on a number of investigations beginning in the autumn of 1952 comparing, under different humidities, different samples of DNA (such as pig thymus, squid sperm, and wheatgerm DNA). Their observations confirmed what Franklin and Gosling had concluded that the phosphate groups were found on the outside of DNA. They then extended the study to look at the effect of undried preparation of live trout sperm to support the hypothesis that the drying process had no affect on the in vivo structure which it subsequently confirmed. The importance of these comparative studies was affirmed by the growing number of samples that were collected that not only showed para-crystalline patterns but also the A-type of DNA. This indicated that the crystalline appearance of DNA was not laboratory induced but occurred in biologically active samples and that the work of Franklin and Gosling would have universal applications.
