The Society was saddened to learn of the death of Member Leslie Iversen FRS on 30 July 2020, aged 82. Completing a PhD in Pharmacology at Cambridge, he subsequently worked with Julius Axelrod at NIH and with Stephen Kuffler at Harvard. In 1970 he returned as the first director of the MRC Neurochemical Pharmacology Unit at Cambridge but left in 1983 to head the Merck Sharp & Dohme Research Neuroscience Centre at Harlow. Retiring in 1995, he became, until 2004, Director of the Wolfson Centre of Age-Related Diseases in Oxford. Iversen was at the forefront of research on neurotransmitters and neuropeptides, particularly substance P and cholecystokinins. In his early work he was the first to describe GABA uptake into inhibitory nerve endings in the mammalian brain. Leslie Iversen was a member of The Physiological Society from 1969. He was elected a Fellow of the Royal Society in 1980.
