Artemy Lebedev has an interesting history of the typewriter keyboard, concentrating on the Russian version.
The Russian letterkey layout originated from America in the late 19th century. The author has failed so far to find any credible evidence of the first company to produce typewriters with this layout, let alone its authorship. The only thing definitely known is that all firms that produced typewriters with the Russian key layout employed the same one— ЙIУКЕН (or ЙЦУКЕН after the reform of the Russian language) that was dubbed “Standard”.
It’s fascinating to see the reproductions of early keyboards, and to learn that in the prerevolutionary version “the numerals row lacks one, zero and three that would be replaced with I, О and З respectively.” And here’s a fun fact:
The first typewriter (the Yanalif model) was produced in the USSR in Kazan only in 1929. At first it was manufactured with Latin (!) letterkeys. It means that for at least 30 years after being put on the market all typewriters with the Russian font had been made abroad.
