The Society is deeply saddened to learn of the death in Melbourne, Australia, of Honorary Member Geoffrey Burnstock FRS FMedSci AC on 2 June, aged 91. Born and educated in London, he started his academic career in Australia, returning to the UK in 1975 to succeed J Z Young as Professor of Anatomy at UCL. He retired formally in 1997 but continued to be actively involved in research programmes there until 2017. Burnstock ‘s research on the autonomic nervous system led him to propose the theory of NANC (non-adrenergic non- cholinergic) neurotransmission, from which he developed the influential concept of purinergic signalling. Burnstock’s work, and that of his many  students and  co-workers from around the  world,  ranged widely from basic mechanistic investigations of central and peripheral autonomic control, to a broad range of clinical studies including cardiovascular, urogenital, neurological, renal and obstetric collaborations. Throughout he encouraged industrial collaborations at every level. A Society Member from 1965, Geoffrey Burnstock became an Honorary Member in 2003. Read his obituary in Physiology News here.
