Carrier, Jean Baptiste, 1756-94, French Revolutionary. An extreme Jacobin, he demanded the establishment of a revolutionary tribunal, and, as a revolutionary representative to Nantes in the Reign of Terror, he instituted noyades, or wholesale drownings, and committed other atrocities. Although he was denounced to the Convention, of which he was a member, and was recalled to Paris, he temporarily escaped punishment during the Thermidorian reaction (July, 1794; see Thermidor). In November, however, he was tried by the Convention and executed.
Carrier, Willis Haviland, 1876-1950, American engineer who played a key role in inventing air conditioning, b. Angola, N.Y., grad. Cornell (M.E. 1901). Working for the Buffalo Forge Co. (1901-14), he developed (1902) a dehumidifier and discovered that circulating air over cold pipes not only removed water from the air but cooled it. He soon refined his concept, and his company set up (1907) a subsidiary to exploit his ideas. In a 1911 paper Carrier outlined the scientific underpinnings of air conditioning and explained its main design features. In 1915 he and several fellow workers founded the Carrier Corp., and he served as its president (1915-30) and chairman (1930-48). Often called the father of air conditioner, Carrier eventually held more than 80 related patents, and his company became one of the industry's major manufacturers.
