A key idea was that data could be coded numerically. Hollerith
determined that if numbers could be punched in specified locations on
a card, in the now-familiar rows and columns, then the cards could be
counted or sorted mechanically and the data recorded. A description of
this system, An Electric Tabulating System (1889), was submitted by
Hollerith to Columbia University as his doctoral thesis, and is
reprinted in Randell's book.[2] On January 8, 1889, Hollerith was
issued U.S. Patent 395,782,[3] claim 2 of which reads:
The herein-described method of compiling statistics, which
consists in recording separate statistical items pertaining to the
individual by holes or combinations of holes punched in sheets of
electrically non-conducting material, and bearing a specific relation
to each other and to a standard, and then counting or tallying such
statistical items separately or in combination by means of mechanical
counters operated by electro-magnets the circuits through which are
controlled by the perforated sheets, substantially as and for the
purpose set forth.
