Original Odhner arithmometer / calculator Model M602 - No 5
From Sweden, Göteborg.
The Arithmometer was the first digital mechanical calculator that was strong and reliable enough to use in an office environment on a daily basis. This calculator allowed you to directly add and subtract two digits and to perform long multiplications and divisions effectively by using a movable accumulator for the outcome. Patented in France in 1820. The robust design led to a strong reputation concerning reliability and accuracy and made it an important actor in the transition from human computers to calculators that took place in the second half of the 19th century.
