Today's selection -- from Empire of Ink by Alex Wright. The 1832 invention of the rotary press:

“One day in 1832, a young man from Boston named Josiah Warren caused a public stir in New York when he unveiled his new invention: a prototype rotary printing press. A brilliant polymath, committed anarchist, and "crank of nearly the first order," in the words of his biographer Crispin Sartwell, Warren was also a printer by training. He had recently returned to the East Coast with his young family after a two-year stint living in the experimental utopian community of New Harmony, Indiana. Initially fascinated with the community's radical, quasi-socialist approach to cooperative living, he had grown disillusioned with the conformist pressures of living in such an environment, and now he had come back to the bustle of urban life to find a new path forward. 

“A prolific writer and inveterate tinkerer, Warren experimented constantly with new philosophies and ways of life, different literary styles, and tools for self.expression: for example, he experimented with using small caps (a typographic style using uppercase letters sized to the height of lowercase) for varying degrees of emphasis, using gratuitous helpings of exclamation marks in ways chat might have made Tom Wolfe blush, and constructing a sophisticated system for indexing that allowed readers to follow a particular theme throughout the length of a book–a kind of rudimentary hypertext. He also invented a lamp that burned lard rather than tallow; devised a new form of musical notation: and prototyped an image reproduction method he called ‘Universal Typography,’ which helped lay the groundwork for stereotype printing. But his most consequential invention was the new press he unveiled that day in New York. 

“Even in its earliest incarnation, the rotary press was a technological marvel, capable of turning out sixty pages a minute, more than ten times faster than traditional hand-pulled presses. Dispensing with the traditional approach of printing pages one sheet at a time on a flatbed plate, it fed a continuous roll of paper through a series of cylinders. Its design was deceptively simple–consisting of three rollers, a few pulleys, and a self-inking device–so simple, in fact, that Warren did not bother to file a patent. The first time he had demonstrated the machine in Indiana, a group of printers panicked. As his son George later recalled, "’hey had never seen a press that would print more than four to six copies per minute and they were going to be d–m if any bloody press should take the bread out of their mouths by doing the work in no time.’ They promptly cried to sabotage it, forcing Warren to haul it back home. But when he later reassembled the device and demonstrated it in New York, it drew admiring crowds.

“For Warren, this was more than just a mechanical invention; it was part of a larger project to put his philosophical ideals into practice. Two years earlier, he had penned an essay entitled ‘Reduction in the Cost of Printing Apparatus,’ where he laid out his vision for radically expanding access to printing cools for the general public. ‘At this time, 1830, the means of printing are so expensive, that the great mass of the people are almost totally deprived of their use–while the wealthy few (by their capital or influence,) wield this mighty engine, to increase their own power, and to weaken that of others.’ While the number of newspapers had been growing steadily, and growing numbers of ordinary citizens had started to find their voice in print (as we have seen in the previous chapters), Warren envisioned a far more radical expansion, in which vast numbers of people would have ready access to their own personal printing presses. He was convinced that such a development would lead to a great outpouring of individuality and equip people to reach their full potential for self-expression and civic participation. The rotary press was to be the first step in a great march of technological progress that would gradually lower the barriers to entry for the general public to express themselves on the printed page. 

“Warren's machine was just a prototype, but it epitomized a larger technological turning point. In the decades to come, American printing would be transformed not only by faster, more powerful presses but by equally momentous changes in how paper itself was made. From steam-driven rotary machines to the mass production of wood-pulp newsprint, advances in both press and paper technology together reshaped the economics of publishing, removed bottlenecks that had constrained growth for centuries, and paved the way for the mass-market newspaper. This chapter explores these deeply intertwined stories. 

“Among the audience watching the New York debut of Warren's rotary press was Robert Hoe, an English-born carpenter turned printing press maker whose company built the popular Washington handpress. Hoe had already begun experimenting with a rotary concept based on earlier work by Friedrich Koenig and David Napier, but while those devices also used a cylindrical device to apply ink to paper, they relied on single sheets and a flatbed mechanism. Warren's use of a continuous paper roll signaled a breakthrough, as the paper wound from cylinder to cylinder, with metal ‘fingers’ gripping it firmly along the way. Hoe's company had also beep. experimenting with a new industrial innovation: steam power (which Koenig had already implemented in his landmark printing press installation for The Times of London). Hoe took Warren's rotary concept and fused it with Napier's cylinder mechanics and Koenig's steam-powered innovation, to create the first fully industrialized rotary press. The Hoe press would go on to become a stalwart of big-city printshops across the United States and Europe and fuel the rise of the city's penny press–the direct precursor of twentieth-century mass media newspapers. 

“Alas, Warren's contributions to the rotary printing revolution have been largely obscured–not least because he never filed a patent. Looking back, one cannot help but wonder what this committed, deeply idealistic anarchist would have thought of the use to which his pioneering invention would ultimately be put: not to liberate the masses with the tools of free expression but to help large media conglomerates accumulate and consolidate power.”
