Burroughs

The Burroughs Adding Machine Company moved to Detroit in 1904 and was once the largest adding-machine company in the United States. William Seward Burroughs founded the company when he invented the Burroughs Registering Accountant in the 1880s; it was the first practical adding-listing machine that printed calculations on paper tapes. The company partnered with the Sperry Corporation in the 80s and is now called Unisys. Although the company is now headquartered in Blue Bell, N.Y. It currently still occupies the old Burroughs factory and office space in Plymouth, Mich.
