Air conditioning is something many of us take for granted, but it’s actually been around for less than 100 years! Air conditioning was originally invented by a New York engineer named Willis Carrier in 1902 in order to help the Sackett-Wilhelms Lithographing and Publishing Company in Brooklyn. The company needed a way to control the temperature to avoid misaligned printing and wrinkled paper on hot days. While Carrier continued to create many different air conditioners, the type we are used to seeing today wasn’t invented until 1931, when H.H. Schultz and J.Q. Sherman introducted the window air conditioner.
