Vintage photos of:
Washington, D.C., circa 1919. "George Parezo & Co., Ninth Street N.W." An electrical appliance store in the early years of that retail category (top sellers included irons, coffeepots, vacuums, table lamps and toasters), on the eve of the emergence of a new a mass communications medium.

Circa 1880-1899. "Majestic Building, Detroit." And a good view of one of the "moonlight tower" arc lamp standards whose base can be seen in the previous post. Some of these towers are said to have made their way to Austin, Texas, where they are the sole remaining examples of their kind. View full size.
A device for measuring and recording the magnetization parameters in thin magnetic films used for computer storage elements. It was designed and built in the Burroughs Corporation's Paoli, Pennsylvania Research Laboratories ca. 1963 by my grandfather and his research group and patented in 1966 (patent No. 3254298). One of four photographs of the device recovered from my grandfather's lab notebooks. View full size.
