On this day, November 26 in the year 1876, the inventor of modern electric air-conditioner was born in New York, USA. His name was Willis Haviland Carrier, founder of Carrier Corporation.
Willis Carrier obtained his bachelor’s degree in mechanical engineering from Cornell University where he studied on scholarship. After graduation, he joined Buffalo Forge Company. While working on the problem of indoor humidity, he came up with a proposal to install a device that would control not only humidity but also temperature, air circulation and ventilation as well as cleanse the air. In 1906, he was granted U.S. Patent for an Apparatus for Treating Air – the first spray type air-conditioning equipment. Later, he made many improvements in the apparatus and came up with the “Rational Psychrometric Formulae” which became the basis for today’s Magna Carta of Psychrometrics.
In 1915, Willis Carrier co-founded Carrier Engineering Corporation. His invention found application not only in factories and buildings but also in private homes. This paved the way for people to move to sunbelt areas such as Florida, Texas, and California. In 1930, the company merged with Brunswick-Kroeschell Company and York Heating & Ventilating Corporation to form Carrier Corporation.
Willis Carrier died in 1950 at the age of 73. He married three times but had an only son. At present, Carrier Corporation is a subsidiary of United Technologies. In 1998, he was included in Time magazine’s 100 most influential Persons in the 20th Century. He was previously inducted into the National Inventors Hall of Fame.
