Heading off to see a summer blockbuster? Thank the early 20th century movie hero who kicked off the phenomenon. Not Superman. Not Captain America. Not even Rin Tin Tin.
William Carrier.
In 1902, the young engineer was working for a heating outfit called Buffalo Forge. That company was approached by Sackett & Wilhelms, a print shop in Brooklyn that was facing a dilemma. Four-color printing meant paper had to be inked four separate times, with each run laying down a different hue. Thanks to humidity, sheets would often shrink or expand in the interim between inkings, making the finished image a mess. What could be done?
Carrier came up with a way of “conditioning” the air in order to keep the temperature and moisture level steady. You can probably guess what he called his invention, writes Lenore Skenazy.
