My friend and collaborator Stephen Herbert, who has died aged 71, was a moving image historian who spent a number of years as head of technical services at the BFI Southbank cinema in London, also working for the BFI’s Museum of the Moving Image.
Later on, his knowledge of early visual media was sought out by academics, museums, programme makers and film producers, and his expertise in all things to do with the Victorian photographer Eadweard Muybridge led to a visiting research fellowship at Kingston University.
