He was born on 8 September 1918, son of William Thomas and Maude Henrietta Barton. In 1938 he entered Imperial College, University of London, where he graduated in 1940 and obtained his Ph.D. in Organic Chemistry in 1942. From then to 1944 he was a government research chemist, from 1944 to 1945 he was with Albright and Wilson in Birmingham. He then became assistant lecturer in the Department of Chemistry of Imperial College, and from 1946 to 1949 he was ICI Research Fellow. During 1949 and 1950 he was Visiting Lecturer in the Chemistry of Natural Products, at Harvard University, and was then appointed Reader in Organic Chemistry and, in 1953, Professor at Birkbeck College. In 1955 he became Regius Professor of Chemistry at the University of Glasgow, in 1957 he was appointed Professor of Organic Chemistry at Imperial College.

In 1950, Professor Barton showed that organic molecules could be assigned a preferred conformation based upon results accumulated by chemical physicists, in particular by Odd Hassel. Using this new technique of "conformational analysis", he later determined the geometry of many other natural product molecules. Conformation generally means structural arrangement. ...
