The Harold Vyvyan Harmsworth Professorship is an endowed chair in American history at the University of Oxford, tenable for one year. The Harmsworth Professorship was established by Harold Sidney Harmsworth, 1st Viscount Rothermere (1868–1940) in memory of his son Harold Vyvyan Alfred St George, who was killed in the First World War, and whose favourite subject was history. Lord Rothermere also established a Harmsworth Professorship in imperial and naval history at Cambridge University in honour of his son Vere, who was killed in the same war. The King Edward VII Professor of English Literature at Cambridge University was endowed by Sir Harold Harmsworth in memory of King Edward VII, who died in 1910.

Thomas Jefferson Wertenbaker was a leading American historian and the second Edwards Professor of American History at Princeton University.
