The International Biographical Dictionary of Computer Pioneers is more than a who's who in computer science and development. It presents biographies of 240 innovators in the field of computing, from Charles Babbage to Alan Turing, and Howard Aiken to John von Neumann, and explains their contribution to computer science. Computer Pioneers includes those who have played a supportive role such as enlightened managers, financiers, or teachers as well as those individuals central to the development of computing. Accompanying each biography is a bibliography in two parts: works by the entrant and works about the entrant. An appendix provides information on other sources of biography from standard reference books to oral history collections. The book ends with a comprehensive index.
