HEAT WAVE: Modern Air Conditioning Was Invented for Paper and Ink's Sake, Not People's!

On July 17, 1902, Dr. Willis H. Carrier developed and later patented the first modern system to provide man-made control over temperature, humidity, ventilation and indoor air.

The first modern air conditioning system was installed at a Brooklyn, NY printing plant in the summer of 1902, to help stabilize the temperature and moisture in the air so that the dimensions of the paper would remain constant and the different color inks would line up correctly. Since then, the technology has changed our lives in both dramatic and subtle ways.
