Donald Watson

The next breakthrough came in 1952, when Francis Crick and Donald Watson applied X-ray diffraction techniques to DNA and elucidated its structure, as shown schematically in Figure 2.5. They showed how its now famous double helix is held together via a series of unusually strong dipole-dipole interactions between precisely positioned organic bases situated along the DNA polymer s backbone. 

Another series was subsequently launched by John Wiley Sons, who also assembled a distinguished advisory board (Fig. 9), theirs consisting of Tom Chilton and his visionary subordinate, Tom Drew, from Du Pont, Donald B. Keyes of the University of Illinois, Kenneth M. Watson of Universal Oil Products near Chicago, and Olaf A. Hougen of the University of Wisconsin. The latter two authored in 1931 a salutary text on Industrial Chemical Calculations, precursor of their pivotal three volumes on Chemical Process Principles. Hougen and Watson held that process problems are primarily chemical and physicochemical in nature, whereas unit-operation problems are for the most part physical [46]. (Incidentally, Wiley Sons did not claim for their series even the second edition of Hitchcock and Robinson s book, which they published.)... 

With the post-war reconstruction chemical engineering at UCL moved from the Science to the Engineering Faculty and in 1947 had a staff of four academics (H.E. Watson, M.B. Donald (now a Reader), J.P. Mullen and a new assistant lecturer, P.H. Calderbank), its old laboratory steward (R.S. Potter) and an intake of 24 undergraduates H.E. Watson retired in 1951 to be succeeded by M.B. Donald, the fourth Ramsay Professor.
