Carrier invents air conditioner

In 1902, Willis Haviland Carrier completed drawings for what came to be recognized as the world's first scientific air conditioning system. In 1901, he started working in research and development for Buffalo Forge Co., a leading manufacturer of fan heating equipment. Shortly, he was assigned to solve a problem for a printing plant where humidity control was necessary for paper handling in the machinery. The system he designed with cooling coils was installed at the Sackett and Wilhelms Co. in Brooklyn in 1902, though it was retrofitted to an existing hot-blast heating system instead of being properly designed from scratch as a total system. However, Carrier went on to improve on his invention, and began the air-conditioning industry.
