re: history of invention

With hot weather coming, a reminder of where those air conditioners came from.



Willis Haviland Carrier (November 26, 1876 – October 7, 1950) was an American engineer, best known for inventing modern air conditioning. Carrier invented the first electrical air conditioning unit in 1902. In 1915, he founded Carrier Corporation, a company specializing in the manufacture and distribution of heating, ventilation, and air conditioning (HVAC) systems.

In Buffalo, New York, on July 17, 1902, in response to an air quality problem experienced at the Sackett-Wilhelms Lithographing & Publishing Company of Brooklyn, New York,[6] Willis Carrier submitted drawings for what became recognized as the world's first modern air conditioning system. It was so humid in summer that the paper grew and shrank, which resulted in poor quality images, because the color printing process involved running the same piece of paper up to four times, each with a different color ink.[7]
