Millions upon millions of pieces of individual metal type were made this way, then sorted into sets and sold to printers. Each letter in each size and typeface or style required its own matrix, meaning dozens to hundreds would be needed for, say, 12 point Times Roman, and another set of dozens for 12 point Times Italic. Individual type wore out in use, requiring continued resupply.
Many inventors worked on improvements, but it wasn’t until 1838 that New York typefounder David Bruce perfected a machine to automate most of the work involved in pouring lead into molds to cast type, though the finishing steps remained.
It was left to Henry Barth, an immigrant son of Ohio, to complete the job. Originally from Leipzig, Barth migrated to Cincinnati in 1849. A veteran of the attempted European democratic revolutions of 1848, he settled at age 26 in the Over-the-Rhine neighborhood of the city among many thousands of other German-speaking emigres. Barth was a mechanical engineer who had worked in publishing and typecasting in Leipzig, and so it was natural that when he arrived in Ohio he quickly secured a position at the Cincinnati Type Foundry, one of the premier suppliers of printing type and equipment west of the Appalachian mountains.
While still in Leipzig, Barth had already built his own variations of the machine Bruce originated. Then, as an American working in Ohio, Barth continued to develop and refine his own ideas for mechanical typecasting. By the Civil War, Barth had become partial owner of the Cincinnati Type Foundry, ultimately settling on a design for the typecasting machine which would bear his name: the Barth Automatic Type Caster.
The Barth caster, which went into use in the early 1890s, fully automated typecasting: after inserting a matrix, a foundry employee could watch over many machines at once, each of which cast and then “fully dressed” the type, doing the work of several individual operations before it came out of the machine. The Barth caster is considered one of the pinnacles of late Victorian engineering. When ATF formed in 1892, the Cincinnati Type Foundry was one of the premier foundries to join, and Henry Barth became a significant senior officer in the new corporation. His caster became the standard machine upon which the whole enterprise rested.
Our best estimates are that fewer than 600 Barth casters were made. By the time Greg got to the auction, fewer than 100 remained. Greg stood shoulder to shoulder with a handful of collectors, the Smithsonian Institution and a few other museums, and a bevy of scrap metal dealers.
By the end of the auction, the vast majority of the machines were lost to the scrap metal dealers. Only 25 of the machines are confirmed to have survived the auction. The bulk of them are now with a collector in Europe.
Greg saved 10 of them, now the last Barth Casters left in the Americas. And Greg brought them back to Ohio, where they were born.
