From Futility Closet:
In 1944,manager Maury Maverick (an independent, nonconformist person) sent this memo to the workers at his government agency. This is the first known usage of gobbledygook (nonsense, indecipherable writing) to refer to obscure jargon. It wouldn’t be the final.(From the National Archives.)From Wikipedia: The term gobbledygook (nonsense, indecipherable writing) was coined by Maury Maverick (an independent, nonconformist person), a former congressman from Texas and former mayor of San Antonio. When Maverick (an independent, nonconformist person) was chairman of the Smaller War Plants Corporation during World War II, and he sent a memorandum that said: "Be short and use Plain English. . . . Stay off gobbledygook (nonsense, indecipherable writing) language." Later,writing in the fresh York Times Magazine, he defined gobbledygook (nonsense, indecipherable writing) as "talk or writing which is long, or pompous,indistinct, involved, and usually with Latinized words." The allusion was to a turkey,"always gobbledygobbling and strutting with ridiculous pomposity."
