- Patent Model of Edmondson's Circular Calculating Machine, 1883 - Mechanical calculators used gears, cogs, levers, and rotating drums to solve mathematical problems indirectly. While Edmondson's Circular Calculator was rugged and reliable, its "stepped drum" system required people to slide plates and levers, making it difficult to master and time-consuming to operate. By the late 19th century, improved adding machines became popular, helping to reduce the common errors of human calculation.

- Calculating and Printing Machine, Made by Leon Bollee, France, circa 1900 - Leon Bollee manufactured automobiles in France from 1895 until his death in 1913. He also invented a series of mechanical calculating machines -- forerunners of the electric calculator. Bollee made an important contribution to aviation when he provided Wilbur Wright with workspace and a crew of mechanics for Wright's successful airplane demonstrations at Le Mans, France, in 1908.

- Burroughs World Headquarters, circa 1971 - William Seward Burroughs and three other co-founders established the American Arithmometer Company in 1886 to produce simple addition and subtraction machines. Over the years, the company--later known as the Burroughs Corporation--innovated and expanded. Mergers with companies such as Moon-Hopkins and Sperry in the 20th century helped Burroughs become a leader in the calculating--and later computing--industry.
