The Role of Governments in the Spread of Novel Computing Devices in the Nineteenth and Early Twentieth Century United States

Abstract

Nineteenth and early twentieth century American governments—local, state, and national—profoundly shaped diffusion of novel mathematical instruments. The federal government ran an office that judged what inventions were patentable and a legal system for those who defended or challenged patent rights. Governments at all levels employed inventors. Sometimes new laws required extensive calculations promoting invention and sale of computing instruments. Governments were customers for mathematical instruments ranging from teaching apparatus to adding and calculating machines to harmonic analyzers to tabulating machines. They not only bought goods, but set standards for what they would purchase. Government buyers also offered testimonials to businesses. From the 1890s, ant.itrust legislation led to some federal government oversight of corporations. Historians usually rely on documents to tell this story. This paper begins from objects—a few known only from patent descriptions, but most surviving in museum collections. This perspective complements rich existing accounts.
