Following some years of declining health, Professor Maurice Crosland passed away on 30 August 2020 at the age of eighty-nine. Author of four influential scholarly monographs, Maurice played major roles in the British Society for the History of Science during the 1960s and 1970s as an active Member of Council, Honorary Editor of the British Journal for the History of Science (1965–71) and Honorary President of the society (1974–6). His academic career began in 1963 with his appointment to a lectureship in the History & Philosophy of Science at the University of Leeds. In 1974 the by-then Reader in History of Science secured a £100,000 Nuffield Foundation Grant with which to establish, for the first time, a dedicated history-of-science group at the University of Kent at Canterbury. Appointed Professor of the History of Science and Director of the Unit for the History, Philosophy and Social Relations of Science (known as the ‘History of Science Unit’ or simply ‘the Unit’), his objectives during the five-year Nuffield-funded period were to focus on promoting the research activities of the new group, build up much-needed library resources in a university which was barely ten years old, and effect a transition to a research and teaching Unit that would offer modules to undergraduates in each of the three principal faculties (Humanities, Natural Sciences and Social Sciences). His own research centred on French science during and after the Napoleonic period, with particular emphasis on the history of chemistry and the formal institutions and informal networks of Parisian science. In 1984 his work was recognized with the American Chemical Society's award of the Dexter Prize, a rare achievement for a British scholar.

A century ago the work of laying the first Atlantic cable and the measurements which were needed of the electrical resistivity of the copper, as well as of the resistance of the cable itself, had shown the inadequacy of the resistance standards which then existed.
