Claudia Schnurmann is a German historian. She studied Medieval and Modern History, German Studies, and Art History at the universities of Cologne and Göttingen. In 1988, she completed her doctoral thesis at Göttingen under Hermann Wellenreuther, focusing on the English trade of Cologne merchants in the 16th century. In 1997, she habilitated at Göttingen with a thesis on the English and Dutch in the American-Atlantic world from 1648 to 1713. The University of Göttingen granted her the Venia legendi for Medieval and Modern History. Schnurmann was a visiting professor at the Moore Institute for Research in the Humanities and Social Studies at the National University of Ireland Galway in 2001/2002 and 2002/2003. Since October 2003, she has been a professor of North American and Atlantic history at the Historical Seminar of the University of Hamburg. Schnurmann’s research focuses on Hamburg-American relations in the 18th and 19th centuries. Other areas of her research include the correspondence of Franz and Mathilde Lieber (1828–1871) as well as the diaries of George Peterson Jenkins (1849–1897) and Francis A. Hester (1820–1899). In her habilitation, she questioned, among other things, “the notion that the Dutch were displaced from the American region in the second half of the 17th century.” She published a work in 2014 on the German-American couple Francis Lieber and Mathilde Lieber, compiling over 11,000 letters from numerous archives. In 2018, she published another work on the couple, in which the focus was on the love between them as revealed through their correspondence. In 2001, she was awarded the Foreign Language Book Prize by the Organization of American Historians for her book Atlantic Worlds, English and Dutch in the American-Atlantic World 1648–1713, recognizing it as the best non-English book on American history for 2000/2001. Since October 2011, she has been a full member of the Academia Europaea. Schnurmann is also a co-editor of the Yearbook for European Overseas History. She was married to Hermann Wellenreuther.
