In 1902, shortly after joining the Buffalo Forge Company, Willis Carrier had a momentary insight while standing on a train station in Pittsburgh, which would lead him to develop his first air conditioner system. The oft-repeated story of this discovery involves something of a paradox: Carrier, surrounded by fog, realized that he could dry air by adding water to warm, humid air to create fog. He realized that if he saturated the air with water, he could control the temperature of that saturated air by passing it through a cool water spray that caused the moisture of hot, humid air to condense and leave the air stream. Although the cooling of air had been demonstrated by Gorrie, Franklin and others, Carrier solved the problem of removing humidity from the air.
