Frank Stephen Baldwin,
An Interview with the Father of the Calculating Machine
(1919)
“ I contrived the plan of substituting one cylinder for the nine cylinders in that machine, making a working model, which is now in the Patent Office at Washington.It was on this model that William Seward Burroughs, later of Burroughs Adding Machine fame, did some work for me in a small general machine shop, which he, with his father, had in St Louis. Not until about 1880 did Mr. Burroughs start work on his own adding machine with a keyboard set-up. The meteoric success of the business that bears the Burroughs name is history. ”
