Hammond Multiplex (1913-1927)

Hammond Multiplex

The Hammond Multiplex, introduced in 1913, was a radical departure from standard typewriters like a Remington or Underwood. Instead of having long metal arms for each letter that slammed into the paper, it used a single, curved typing wheel that zipped into position before a small internal hammer struck from behind, pressing the paper against the ink ribbon.This clever design gave the "Multiplex" its standout feature: the ability to hold two different font wheels at the exact same time. A writer could swap from italics to regular print, or English to Greek, in just a few seconds by simply twisting the dial on top. This made it the absolute favorite tool for scientists, language experts, and famous authors who needed special symbols or multiple languages in a single document.
