David Hey (1938-2016) was one of the leading local and regional historians of our age and the author of a number of highly regarded books on the practice of local history. His work on surnames was pioneering and he was amongst the first to identify the potential of DNA in historical studies. In this collection of essays in David's memory, friends and colleagues celebrate his commitment to the landscape, economy and society of south Yorkshire - especially Sheffield - and Derbyshire, which together make up 'Hey country', the area in which he grew up and to which he returned to work. This lively volume will be of interest to anyone who shares David Hey's curiosity for the people, economies and landscapes of the part of England he made his focus. At the same time the essays will prove to be of interest to all those concerned with the workings of English local society and economy. Covering a wide range of subjects and periods, they include accounts of the early English steel industry, Sheffield cutlers, Lord William Cavendish's canny use of his stepson's wardship, the lost woodlands of the Peak District, First World War food production in Derbyshire, south Yorkshire deer parks and a brief history of Little Londons. Fresh research into family and placename history contributes fascinating detail to the mix. The contributors are some of the key researchers in academic local history, including Alan Crosby, Nicola Verdon, John Broad, John Beckett, Ian D. Rotherham, Melvyn Jones, Dorian Gerhold and Peter Edwards. A tribute to David Hey by Charles Phythian-Adams opens the volume.
