Layton's Improved Arithmometer, Dated 1912

$7,855.05

About

A Layton's improved arithmometer by C & E Layton of London, in mahogany case, dated 1912. The Arithmometer or Arithmomètre was the first digital mechanical calculator strong enough and reliable enough to be used daily in an office environment. This calculator could add and subtract two numbers directly and could perform long multiplications and divisions effectively by using a movable accumulator for the result. Patented in France by Thomas de Colmar in 1820 and manufactured from 1851-1915, it became the first commercially successful mechanical calculator.
