thumb|A Powers-Samas accounting machine

The Powers Accounting Machine was an information processing device developed in the early 20th century for the U.S. Census Bureau. It was then produced and marketed by the Powers Accounting Machine Company, an information technology company founded by the machine's developer. The company thrived in the early 20th century as a producer of tabulating machines. It was a predecessor to the Unisys corporation.

Development

Census Bureau

In 1890, the government began leasing tabulating machines from Herman Hollerith's Tabulating Machine Company, to more efficiently, expansively, and accurately produce the national census. In 1900, Hollerith raised the lease pricing. This led the newly formed U.S. Census Bureau to seek other suppliers under its new director, Simon North, in 1903. North returned most of Hollerith's machines, and the Census Bureau began using Charles F. Pidgin's tabulators. These machines proved too slow, so the Bureau undertook to develop its own machine for the 1910 census. The inventor was a member of the Machinery Club and the American Society of Mechanical Engineering through the time of his death on Tuesday, November 8, 1927, at age 57. The New York Times ran a brief paid obituary two days later.

In Europe, Powers established European operations in 1915 through the Accounting and Tabulating Machine Company of Great Britain Limited, and in 1929 renamed to Powers-Samas Accounting Machine Limited (Samas, full name Société Anonyme des Machines à Statistiques, had been the Power's sales agency in France).
