The printing press arrived at a time when literacy was increasing, and political and religious ferment had created a strong demand for information of all kinds, including books, tracts, pamphlets, and devotional materials. In 1450 every book in the world, all of them hand printed manuscripts, would have fit into a single moderately sized modern library, but by 1500 John Man, author of The Gutenberg Revolution, estimates there were already 15 to 20 million. Within a dozen years of Gutenberg’s death there were printing presses in 122 European cities.
As the book points out, Gutenberg was the first to bring together all the elements necessary to mass produce reading material, but he was far from the first to envision movable type. The Chinese had printed books using wooden blocks 700 years earlier, and the Koreans were using metal type by 1234, but the vast numbers of characters needed to produce texts meant they were not viable alternatives to hand written books.
Other key components of Gutenberg’s process were adapted from technology which had existed for centuries. The ancient Romans had used hand operated presses to make grape and olive oil, and skilled craftsmanship had created punches, which would later be used to create letter forms, for coins and jewelry since ancient times.
Gutenberg did invent an ink of just the right consistency, and an ingenious way to rapidly cast multiple copies of individual letters. The author provides some illustrations of this and tries to explain how it worked, but in this case a video is worth a thousand words and there are good examples on the internet to show how it worked.
Creating the letter forms for the punches was exacting work, and it took Gutenberg’s craftsmen over a year to create the 300 forms needed for the first Bible which, it was somewhat surprising to read, was not the first book printed with the new technology. In 1448 in Mainz he created a printed version of a popular Latin primer, and the famous bible came out in 1455.
Gutenberg’s business partners have long been vilified for their behavior, calling in their loans, suing him, taking possession of his press, and even asserting that the whole idea was theirs. This is a complicated story, with many details lost to time, but his partners were entirely within their rights since they had advanced Gutenberg considerable sums of money that he could not repay, and one of craftsmen did in fact make key contributions to the overall design of the press. In any case, Gutenberg was soon back in business, with a new workshop and press, and making a comfortable living printing indulgences and political pamphlets. One of his patrons wisely paid him an annuity to ensure that he only printed complimentary things.
The book also does a good job setting the invention within the complicated and dangerous times of the 15th century, where bishops went to war with each other, mercenaries sacked towns in lieu of payment, and episodes of plague reoccurred regularly. The printing press became an essential tool for Martin Luther’s Reformation, which would not have been able to spread so far so fast without it. He churned out vast numbers of books and tracts, writing in German to reach the widest possible audience, and his translation of the bible is still the one most Germans know today.
The Gutenberg Revolution has been compared to Dava Sobel’s Longitude as a technology history designed to reach a wide audience of non-specialists. I think this is a fair comparison, and the book packs a surprisingly large amount of information into fewer than 300 pages. Sometimes the style is a bit too glib, a sort of gee whiz approach that I felt was unnecessary. Still, for anyone with an interest in this subject who wants to gain more understanding about one of the seminal inventions of civilization, this is a good place to start.
