The Society regrets to hear of the death of David Armstrong, emeritus Professor of Physiology at the University of Bristol, after a long illness following a stroke. David was internationally recognised for his work on how the brain controls goal-directed movement, using a combination of anatomical, physiological and behavioural methods. Completing a PhD in Canberra with John Eccles, he moved to Bristol where he became head of Physiology in 1990. A Society member from 1969, he was an editor of The Journal of Physiology between 1979 and 1986. After retirement, David took up a second career in the Orkneys of ornithological photography.
