Next time you’re cruising down the road in air conditioned comfort or sleeping soundly on a hot, humid night, take a moment to give thanks for the publishing industry. Willis Carrier invented air conditioning in 1902 to combat inking problems for his employer, the Sackett-Wilhelms Lithographing & Publishing Company in Brooklyn, New York. Believe it or not, its initial intent was not to improve comfort levels for people but was instead to control humidity so ink would adhere to paper more consistently. TK
