Elected F.R.S. 1976
W. M. ‘Gregor’Henderson belonged to the great tradition of veterinary involvement in the control of epizootic diseases that was such a feature of the middle part of the twentieth century. He was one of the pioneers of research into the virology of foot–and–mouth disease and the development and application in the field of vaccines to control it. Throughout his career, first as scientist, latterly as administrator, he maintained a close interest in the animals to whose wellbeing research was directed and in the work of the practising veterinary surgeons who ultimately translated veterinary science into veterinary practice.
