Pieter Geyl (1887-1966) was undoubtedly one of the most internationally renowned Dutch historians of the twentieth century, but also one of the most controversial. Geyl was an early example of a ’public intellectual’ and remains one of the most influential thinkers on history of all time. This volume re-examines Geyl’s time in Britain, his relationship to both the Netherlands and Britain, and sheds new light on his multifaceted work as a historian, journalist, translator and political activist, his contemporary networks, as well as on his lasting legacy for British views of German, Dutch and Belgian history.
