Now largely forgotten, Henry Enfield Roscoe was one of the most prominent chemists and educational reformers in Victorian Britain. His contributions include transforming Owens College into Victoria University, now the University of Manchester, campaigning for the reform of technical education, serving as the Liberal MP for South Manchester, and cofounding the Lister Institute of Preventative Medicine. In this detailed biography, authors Morris and Reed provide a timely and original contribution to the history of nineteenth-century British science and its relation to education, industry, and government policy, highlighting Roscoe's significant legacy as one of the leading scientists of his generation.
