James G. O'Hara, Ph.D., (1979), University of Manchester, is an historian of science and technology. During his career, he has taught and done research in Delft, Regensburg, Stuttgart, Munich (Deutsches Museum), Hamburg and Hanover. His research interests include the edition of manuscript papers of historical personages in science and technology (17th–19th centuries). Between 1987 and 2013, he co-edited five volumes of Leibniz’s correspondence in mathematics, science and technology at the Gottfried Wilhelm Leibniz Library (Hanover).
