Who Is the Most Important Historian of the Past 60 Years? | History Today History Today turns 60 this year. To mark the occasion, in our forthcoming December issue we ask a number of distinguished historians to choose their favourite works of history produced in the last six decades, and to name the most important historians of the period. Maybe a bit of an impossible question. Errrr. Ummmm... I'd have to put Paul Kennedy right up there for his 'Rise & Fall of the Great Powers' initially, but there are rather a lot to choose from.
