The invention of air conditioning all began in 1902 as Willis Carrier stood in a foggy train platform in Pittsburgh. Carrier realized that he could dry air by passing it through water, which would then create fog. This meant that air could be manufactured with specific amounts of moisture in it, making it possible to control humidity. Little did Carrier know that his invention would give rise to a multitude of industries that power today's economy and shape our world.
1902 - Willis Carrier designed the world's first modern air conditioning system
