Early Burroughs adding machine

William S. Burroughs (1855-1898)

Burroughs was the son of a mechanic and worked
with machines throughout his childhood. He invented
a "calculating machine" designed to ease the monotony
of clerical work. He was a founder of the American
Arithmometer Company (1886), which later became
the Burroughs Adding Machine Company (1904),
then the Burroughs Corporation (1953) and in 1986,
merged with Sperry Corporation to form Unisys. He
was posthumously inducted into the National Inventors
Hall of Fame.
