Sackett and Wilhelms (c. 1887 - 1945), often as the Sackett and Wilhelms Lithographing and Printing Company, was a lithographic printer based in New York City, and more specifically in Brooklyn. The firm was best known for their printing of chromolithographic illustrations for the satirical magazine Judge, but they also produced broadsides, maps, and books, and were especially active in producing posters to support the U.S. war effort in the First World War. The company's printshop in Brooklyn was notable for being the home to the world's first modern air-conditioning system, designed by Willis Carrier (1876 - 1950), working at the time for the Buffalo Forge Company. Because of humidity in the summertime, paper would shrink and expand throughout the day, causing the colored inks, applied one at a time, to be misaligned. Desperate for a solution, Sackett and Wilhelms turned to Buffalo Forge, who tasked their promising young engineer Carrier with finding a solution, leading him to devise methods for controlling humidity in addition to cooling air.
