The Linotype: The Machine that Revolutionized Movable Type

the gist

The Linotype, invented by Ottmar Mergenthaler and first tested at the New-York Tribune in 1886, let an operator type on a keyboard and cast a whole line of type as a single solid metal slug. Each key released a brass mould called a matrix from a magazine at the top of the machine, and once a line was complete it was poured in hot metal. The matrices were then returned to their places by notches the machine could read. Before this, typesetters had placed individual letters by hand, a slow step since Gutenberg. Newspapers boasted about their machines and called them the century's most marvellous time-saver, and linotypes dominated composing rooms for about a century. Their keyboard's first two columns spell etaoin shrdlu, a signal printers typed to flag a typo. The New York Times retired its last linotypes in 1978.

so what

The linotype was one of the key steps that made mass newspapers cheap and fast, allowing daily papers to grow in size and readership. Its end shows how quickly technology can transform a trade, moving from hot metal to cold type and then computers within decades. It also reveals a hidden craft culture around the machines that shaped how news was produced.

fun fact

Typesetters used the phrase etaoin shrdlu to mark a typo, and it appeared in printed newspapers when mistakes slipped through.
