After graduation from the University of Copenhagen in physics and chemistry, and a period as a high school teacher, Helge Kragh became Associate Professor at Cornell University, Departments of History and Physics. Since 1990 he has held positions as Curator at the Steno Museum for Science and Medicine, Aarhus University, and as Professor of History of Science at the University of Oslo. In 1997 he was appointed Professor of History of Science and Technology at Aarhus University, Denmark. Kragh is a member of the Royal Danish Academy of Science and Letters, the International Academy for History of Science, the European Society for History of Science, the European Physical Society, and the European Academy of Science.

This interesting work would be a useful addition to college libraries. Recommended.
