Richard James Overy is a British historian who has published on the history of World War II and Nazi Germany. In 2007, as The Times editor of Complete History of the World, he chose the 50 key dates of world history.

Alan John Percivale Taylor was a British historian who specialised in 19th- and 20th-century European diplomacy. Both a journalist and a broadcaster, he became well known to millions through his television lectures. His combination of academic rigour and popular appeal led the historian Richard Overy to describe him as "the Macaulay of our age". In a 2011 poll by History Today magazine, he was named the fourth most important historian of the previous 60 years.
