Hajo Holborn

Hajo Holborn (; 18 May 1902, Berlin – 20 June 1969, Bonn) was a German-American historian and specialist in modern German history. He was designated a Sterling Professor of History at Yale University in 1959, the highest academic rank offered by the university.

He studied German history with Friedrich Meinecke at Berlin University, as well as with other eminent historians such as Karl Holl, Adolf von Harnack and Ernst Troeltsch. He earned a Ph.D. in 1924 at the age of 22. After becoming a lecturer of medieval and modern history at Heidelberg in 1926, he was promoted to Privatdozent. His next professional advancement was to Carnegie Professor of History and International Relationships at the private Deutsche Hochschule für Politik in Berlin. He was dismissed from his appointment in 1933 by the Nazi government, but he had already left the country by that time. Several well-known scholars of German and European history in America, including Peter Gay, Theodore Hamerow, Leonard Krieger and Otto Pflanze, were students of Holborn.
