The climate we inhabit is engineered. When Willis Haviland Carrier, a quiet engineer from New York, solved a humidity problem in 1902, he didn't just invent a machine-he unleashed a fundamental force that would reshape human civilization.

This comprehensive biography traces the life of the "Father of Air Conditioning," examining his journey from the elegant simplicity of his Rational Psychrometric Formulae-the mathematical bedrock of climate science-to the massive centrifugal chillers that enabled the age of comfort cooling in the Rivoli Theatre and the U.S. Congress.

Discover how Carrier's scientific precision and entrepreneurial persistence built a global corporation that navigated the Great Depression and World War II, ensuring his invention survived to fuel the post-war boom.

Uncover the profound cultural and economic consequences of his genius: how air conditioning enabled the rise of the modern skyscraper, catalyzed the massive population shift to the Sun Belt, and forever changed our expectations of comfort, productivity, and leisure.
