The Real Reason Air Conditioning Was Invented

While it might seem that the air conditioner was invented by someone who was tired of being hot and sweaty all summer, it actually served a different purpose in the beginning. While Willis Carrier changed the world with his invention, the air conditioner he invented was originally much smaller and was actually invented to keep moist air at a printing plant from wrinkling magazine pages. He successfully used coils to both cool and remove moisture from the air, and would eventually establish the first mass manufacturing plant for air conditioners. Advances in technology eventually yielded the more convenient window air conditioner in the late 1930s, though it remained out of touch for most. Today, almost 90% of U.S. homes have air conditioning.
