About this collection

The Leather Research Photographic Collection consists of images of National Bureau of Standards (NBS) employees engaged in leather research during periods ranging from 1919 to the early 1960s. After the outbreak of World War I, leather became scarce and the search for substitutes began. Leather substitutes produced by industry and tested at NBS included fish skin, porpoise, and sharkskin as uppers for civilian and military shoes and a variety of compositions for soles. [From: Measures for Progress by Rexmond C. Cochrane, p. 175]. In the 1950s, NBS studied the pore structure of leather and the moisture content of leather as a function of humidity at different temperatures. The study was then extended to development of a new method for the determination of water-vapor permeability in leathers. [From: A Unique Institution by Elio Passaglia, p. 234]
