Jacquard's Web: How a Hand-Loom Led to the Birth of the Information Age

Essinger, a master story-teller, describes how Joseph-Marie Jacquard's loom enabled the silk-weavers of Lyons to weave fabrics 25 times faster than had previously been possible. The device used punched cards, which stored instructions for weaving whatever pattern or design was required. These cards can very reasonably be described as the world's first computer programs. Indeed, Essinger shows through a series of remarkable and meticulously researched historical connections—connections never before investigated—that the Jacquard loom kick-started a process of scientific evolution which would lead directly to the development of the modern computer. The book examines a wealth of extraordinary links between the nineteenth-century world of weaving and today's computer age: for example, modern computer graphics displays are based on exactly the same principles as those employed in Jacquard's special woven tableaux. Jacquard's Webalso introduces some of the most colorful and interesting characters in the history of science and technology: the modest but exceptionally dedicated Jacquard himself; the brilliant but temperamental Victorian polymath Charles Babbage, who dreamed of a cogwheel computer operated using Jacquard cards; and the imaginative and perceptive Ada Lovelace, Lord Byron's only legitimate daughter.

Attractively illustrated and compellingly narrated, Jacquard's Webis an engaging and delightful volume. It is an impressive case of historical detective work, one that will leave the reader mesmerized.
