Рэймонд Гослинг: ДНК құрылысын ашуға қосқан үлесі

British physicist

Raymond George Gosling (15 July 1926 – 18 May 2015) was a British scientist. While a PhD student at King's College, London he worked under the supervision of Maurice Wilkins and Rosalind Franklin. The crystallographic experiments of Franklin and Gosling, together with others by Wilkins, produced data that helped James Watson and Francis Crick to infer the structure of DNA.

He was born in 1926 and attended school in Wembley. He studied physics at University College London from 1944 to 1947 and became a hospital physicist at the King's Fund and Middlesex Hospital between 1947 and 1949 before joining King's College London as a research student, from which he eventually received his PhD.

When he arrived at King's College London, Gosling was directed by Sir John Randall to work on the problem of the structure of DNA. Randall was convinced that DNA was the material which transmitted the genetic code. analysing samples of DNA which they prepared by hydrating and drawing out into thin filaments and photographing in a hydrogen atmosphere. although he was probably unaware of the prior work of Florence Bell. After the initial work producing the first x ray diffraction of DNA, Randall reassigned Gosling to work with Rosalind Franklin, who had been just hired to join King's College in 1951. He did this without consulting with Wilkins, a factor which may have contributed to the animosity between the two. During the next two years, the pair worked closely together to perfect the technique of X ray diffraction photography of DNA and obtained at the time the sharpest diffraction images of DNA. They produced the first X ray diffraction photographs of the "wet form B" (B DNA) paracrystalline arrays of highly hydrated DNA. In 1952 Gosling made the best X ray diffraction image of DNA known as Photo 51. This piece of evidence helped Francis Crick and James D. Watson to decipher the correct chemical structure. Crick, Watson and Wilkins shared the 1962 Nobel Prize for Physiology or Medicine on discoveries of nucleic acid structure. Gosling was the co author with Franklin of one of the three DNA double helix papers published in Nature in April 1953. Gosling was not recognized by the Nobel Committee and Franklin had died four years before. When Franklin left King's College, Gosling was reassigned back to work with Wilkins, with whom he formally completed his thesis work. After the first Nature article on the x ray diffraction results leading to the double helix model, he and Franklin (who had by that time left King's College) followed up their DNA x ray analysis with a second article in Nature. His other King's colleagues included Alex Stokes and Herbert Wilson.

Gosling briefly remained at King's College following the completion of his thesis in 1954, but the 1953 work on DNA structure was not, at the time, viewed with the importance it now has achieved, and following his Ph. D., Gosling found no opportunity to continue at King's, although he would have liked to do so. Gosling served on numerous committees of the University of London, notably relating to radiological science, and retained an active professional involvement in medical physics almost to the end of his life.

Gosling and his wife Mary had four sons, the eldest of whom is the furniture designer Tim Gosling. Raymond Gosling died at the age of 88 on 18 May 2015.
