Before the invention of modern air conditioning, hot, steamy weather often meant lost work days and sleepless nights.
Willis Carrier’s slide rule, a circular calculating instrument, was patented in 1881 and manufactured by Kueffel & Esser. At the slide rule’s core is a cylinder, or slide, containing a series of scales. Careful scale alignment yields the precision of a modern calculator. Carrier used this instrument to calculate dew point control, a breakthrough that was the foundation of his invention of modern air conditioning.
Willis Carrier starts the engine that will drive the world’s first modern air conditioning system, installed in the summer of 1902 at the Sackett & Wilhelms printing plant in Brooklyn, New York. This artist’s conceptualization appeared in the August 1954 edition of Steelways magazine, which noted, thanks to Carrier, that “air conditioning spread through the industry like a cool breeze.”
A group portrait of the engineers of Buffalo Forge Company includes Willis Carrier (bottom row, third from right) and his future business partner, J. Irvine Lyle (middle row, sixth from left). Carrier, Lyle and five fellow engineers would launch Carrier Engineering Corporation as an independent entity in 1915.
The invention of modern air conditioning in July 1902 was just the beginning for Willis Carrier, whose contributions to efficient industrial production and enhanced human comfort over the next 50 years were so comprehensive that he became known as “The Father of Air Conditioning.”
Buffalo Forge Company sells Carrier’s “Apparatus for Treating Air” to the Chronicle Cotton Mills of Belmont, North Carolina, and applies it to the mill’s fan-heater ventilating system. It was the first industrial “central station” humidifying system.

Willis Carrier’s Rational Psychrometric Formulae brought science to what had been the often hit-or-miss design of air-conditioning systems, and in the process made Carrier an international name. The chart would be updated and reprinted regularly, serving as an essential tool to generations of engineers and remaining the basis of today’s designs.
Almost from the start, air conditioning became an international phenomenon, with important installations of equipment designed by Willis Carrier reaching from North America to Asia, Europe, the Middle East, Central and South America.

Carrier hires Margaret Ingels as America’s first woman air-conditioning engineer, right around the time that the decision to allow U.S. women the right to vote was being debated by lawmakers. True to Carrier’s pioneering spirit, she was the subject of several articles in national magazines and served on President Herbert Hoover’s Conference on Home Building and Home Ownership in the late 1920s. Ingels also wrote Willis Carrier’s biography, published in 1952.
This iconic photo of Carrier co-founder Alfred E. “Ned” Stacey shows him seated in the company’s Newark, New Jersey, research laboratory shortly after its founding in 1918.

In 1922, Carrier unveiled the first centrifugal chiller, which opened the door to large-scale comfort air conditioning.
On the same day in 1950 that Carrier Corporation completed its 2,000th centrifugal refrigeration machine, Willis Carrier, Chairman Emeritus, visited the Onondaga Pottery Company in Syracuse, New York to inspect his first centrifugal, completed in 1922. The Chief found it in perfect working condition. This picture is thought to be among the last taken of Carrier.
New York City’s “new” Madison Square Garden opened in 1925, employing Carrier centrifugal chillers to cool its patrons and produce a perfect ice surface for professional hockey.

The construction of the Milam Building in San Antonio, Texas, included Carrier central air conditioning, making it the first skyscraper to install comfort cooling as it was built.
In March 1930, Carrier recorded the first sale of its window-sill-height Weathermaster units to the Superheater Company of East Chicago, Indiana, to air condition the second floor of a two-story building. In August, the California Bank of Los Angeles contracted for 490 Weathermasters to air condition its 15-story building. The U.S. Supreme Court was also cooled using 180 Carrier Weathermaster units.
The August 1931 Carrier Courier featured a picture of His Majesty, King Prajadhipok of Siam, with Willis Carrier and a number of company senior executives during the King’s visit to Carrier’s Newark facility. Since that day, Carrier has been a leading supplier of air conditioning to the people and industries of Thailand.
In 1931, the M.V. Victoria, a 13,400-ton Italian motorship designed to run from Italy to Egypt, became the first vessel to make its maiden voyage equipped with Carrier air conditioning.
From the first sale in 1907 of Willis Carrier’s air-conditioning equipment to an international customer, the Fuji Silk Spinning Company of Yokohama, he and his company maintained close ties with Japan. Shown here in 1937, Carrier invited members of the Japanese Trade Commission to Newark Airport for a flight over the metropolitan area in a United Airlines Mainliner. United Airlines was once owned by United Aircraft Corporation, which later became United Technologies Corporation (UTC). UTC became the parent of Carrier in 1979.
When New York City organizers established a World’s Fair committee in 1935, they adopted the motto “Building the World of Tomorrow” and set about attracting companies and technologies that provided for “individual fulfillment and human progress.” Few fit this definition better than Carrier Corporation and modern air conditioning. The Fair opened in 1939 with nearly 1.3 million visitors flocking to the prominent “Carrier Igloo of Tomorrow” in the first 100 days. Inside the Igloo and in the adjacent Hall of Weathermakers, guests learned the steps involved in air conditioning, toured a modern food store using Carrier refrigeration, and viewed an exhibit with Carrier self-contained air conditioning.
With its air conditioning products focused on industrial productivity, Carrier worked tirelessly in support of Allied troops around the globe.
In 1942 Carrier marked the 20th anniversary of Willis Carrier’s invention of the centrifugal chiller. The innovation famous for introducing the general public to air conditioning became, during World War II, a critical component in the efficient production of war materiel.
Carrier’s contributions to the war included refrigeration products that insured the safe delivery and storage of perishable foods served to soldiers “6,000 miles from home.”

Three decades of painstaking work highlighted the original colors of Michelangelo’s masterpiece in the Sistine Chapel but also left it exposed to the elements. Carrier’s preservation work included the use of highly accurate humidity-measuring units, like this one, placed on a ledge about 30 feet above the floor and invisible to visitors.
