Writing the History of Mathematics provides both an intellectual and a social history of the development of the subject from the first such effort written in ancient Greece to recent efforts in the 20th century. A special project of the International Commission on History of Mathematics, this work is the result of more than ten years of collaboration by a team of 32 experts, each writing about the history of mathematics in their own countries or regions, and drawing upon extensive research and archival study. In addition to individuals, such institutions as universities, academies, institutes, libraries, and the like are also covered, including journals, encyclopedias, and other collective projects that promote history of mathematics. The book also includes portraits of twenty-five historians of mathematics.
