Wilkins, Maurice Hugh Frederick, 1916–2004, British biophysicist, b. New Zealand, Ph.D. Univ. of Birmingham, 1940. He conducted research at the Univ. of St. Andrews, Scotland, and at Kings College, the Univ. of London (from 1946 until his death). In Berkeley, Calif., he worked (1944) for the Manhattan Project on the separation of uranium isotopes for use in atomic bombs. Shortly thereafter, he discontinued his research in nuclear physics to concentrate on problems in molecular biology, particularly the structure of DNA (see nucleic acid nucleic acid, any of a group of organic substances found in the chromosomes of living cells and viruses that play a central role in the storage and replication of hereditary information and in the expression of this information through protein synthesis.

). In the early 1950s Wilkins successfully extracted some fibers from a gel of DNA, and began photographing them using X-ray diffraction, but his best sample was passed to another researcher, Rosalind Franklin. On the basis of X-ray photographs prepared by her laboratory that appeared to show a helical molecular structure and from other scientific information, F. H. C.
