Air conditioning
In 1902, the first modern electrical air conditioning unit was invented by Willis Carrier in Buffalo, New York. After graduating from Cornell University, Carrier found a job at the Buffalo Forge Company. There, he began experimenting with air conditioning as a way to solve an application problem for the Sackett-Wilhelms Lithographing and Publishing Company in Brooklyn, New York. The first air conditioner, designed and built in Buffalo by Carrier, began working on 17 July 1902.
Walter P. Chrysler Jr.
In 1934, Chrysler founded the Airtemp division of Chrysler Corporation, which developed the first automotive air-conditioning system. After establishing worldwide distribution, he transferred the patent to the parent company but remained a director. In the following year he became president of the Chrysler Building; he continued in that position until 1953.
