Nobel Prize in Chemistry to be recognized. Some important scientific discoveries are never considered for a Prize, as the discoverers may have died by the time the impact of their work is realized. For example, the contributions of Rosalind Franklin in discovering the structure of DNA: her x-ray crystallography citing the shape of DNA as a helix, were not realized until after her death, and the recipients of the prize were Watson, Crick, and Wilkins. A Chemistry Nobel Prize laureate earns a gold medal, a diploma bearing a citation, and a sum of money. The Nobel Prize medals, minted by Myntverket in Sweden and
