Peirce Accounting Machine Typewriter
Despite its appearance, the Peirce was not actually a typewriter. As its 1907 patent states, it was meant to be used as a perforating machine for bookkeeping and banking, maybe like a check protector, hence its name: the Peirce Accounting Machine. The inventor of the Peirce was John Royden Peirce of New York. The machine was produced ca.1912 by the Peirce Accounting Machine Company which, in 1921, was purchased by the Computing-Tabulating-Recording Company (C-T-R). C-T-R became IBM in 1924.
