Edward Geoffrey Stanley (1799-1869), later Lord Stanley and the 14th earl of Derby, was the first British statesman to become prime minister three times and remains the longest serving party leader in modern British politics. A complex, astute and influential figure, he dominated the political scene during the mid-nineteenth century. Angus Hawkins (1953-2020) was a fellow of the Royal Historical Society and director of the Research Centre in Victorian Political Culture at Keble College, University of Oxford. Professor Hawkins wrote an acclaimed two-volume biography of Edward Geoffrey Stanley, The Forgotten Prime Minister, published by Oxford University Press in 2007 and 2008.
