Modern air conditioning, which arrived in 1902s, is the continuation of this rudimentary principle.  (1876-1950) of Buffalo, New York, developed the fundamental scientific theories of air conditioning. His first system was designed for use in a printing plant. Changes in the temperature and humidity of the plant were causing the ink nozzle to be out of line, which made color printing problematic.
