Burroughs Corporation

The Burroughs Corporation began in 1886 as the American Arithmometer Company in St. Louis selling a adding machine invented by William Seward Burroughs.

The company moved to Detroit in 1904 and changed its name to the Burroughs Adding Machine Company, in honor of Burroughs, who died in 1898. Burroughs grew into the biggest adding machine company in America, although by the 1950s it was selling more than the basic adding machines, including typewriters and computers.

In 1953 the Burroughs Adding Machine Company was renamed the Burroughs Corporation and began moving into computer products, initially for banking institutions. They were always a distant second to IBM. In September 1986, Burroughs Corporation merged with [Sperry Corporation]? to form [Unisys Corporation]?.
