|"A year later  in
Russia, a Swede, Wilgodt Odhner, patented a machine that was almost identical to
Baldwin's. Another one of those historical accidents: Odhner was working for Ludvig Nobel
in St. Petersburg, and while there, with Nobel's support, began work on his calculator.
His plan -- to design and manufacture an industrial calculator that would be small and
simple, easy to operate, and so inexpensive that practically anyone who needed a
mechanical aid would be able to acquire one."
