Derek Shaw obituary

My husband, Derek Shaw, who has died aged 83, worked throughout his professional life in the field of nuclear magnetic resonance (NMR) spectroscopy, a technology which has since become central to the use of MRI scanners.

Derek worked initially for the hi-tech US company Varian Associates as an NMR specialist and product manager in the UK. Fascinated with the possibilities of this technology and its potential medical applications, in 1976 he wrote a book, Fourier Transform NMR Spectroscopy, as a guide to the theory and practice of NMR spectroscopy.
