Glory and Failure
The first attempts to mechanize the production of numerical tables were remarkable in conception coming at a time when a "computer" was in fact a person rather than a machine. This book is the first to provide a unified picture of the difference engines that were the mechanical predecessors of today's digital computer, to emphasize them as part of the history of numerical tables, and to give equal weight to the technical and social aspects of their creation.
Lindgren analyzes the difference engines of Müller and Babbage and the mathematical principles on which they are based, tells the story of how Georg and Edvard Scheutz learned about Babbage's engine, discusses the design and operation of the Scheutzs' machine, and tells why Babbage failed technically and the Scheutzes failed commercially. The often detailed technical descriptions bring to light the inventors' own ways of thinking as work on the engines progressed
Michael Lindgren is Curator at the National Museum of Science and Technology in Stockholm.
"Lindgren's prolific research brings not only their story, but the whole period to life. A 'must read' for Babbage fans."
—Charles Halt Annals of the History of Computing
"The author manages to investigate with equal enthusiasm the lives and deeds of the inventors and the structure and principles of their inventions, giving us a fascinating and unique study of personalities at work and countries in change."
