We are deeply saddened by the death of Professor David Hodgson, who passed away on 29 December 2023 after a long illness.

David Hodgson was a microbiologist of worldwide renown who was a highly valued member of the Department of Biological Sciences and latterly the School of Life Sciences. His generous nature and encyclopaedic knowledge were shared freely with Warwick staff and students alike. His wisdom and humour were also highly appreciated by his colleagues from around the globe, whose esteem was illustrated by the international roll-call of distinguished contributors to the two-day celebration of his career in 2015 when he retired. He had uniquely diverse expertise in the genetics of streptomycetes, myxococci and Caulobacter (types of bacteria unusual in having different cell types), and his fascination with their life cycles and physiology led to intriguing insights into their regulatory mechanisms. His innovative research in this area, which benefited from a Fulbright Senior Research Scholarship to spend a year working with US-based academics sharing his interests, was reflected in his DSc, awarded in 2007. David collaborated with many other academics and was a visiting academic at the University of Surrey. He was an important contributor to collaborative research work at Warwick, in particular playing a key part in a large Warwick-based transnational research programme which helped to redraw the carbon metabolic pathways of Streptomyces coelicolor.
