Model History

The Tarlton Law Library displays patent models, giving a glimpse into the inventions and copyright law of the past.

The Tarlton Law Library ’ s Department of Special Collections has put up an exhibit on patent models in the Susman Godfrey Atrium, which will run through the summer of 2010. Patent models saw their heyday between 1836 and 1870, the period from which most of the models in the exhibit date. Despite devastating fires in 1836 and 1877, by 1880 the U.S. Patent Office had exceeded capacity and banned new models altogether—with the notable exceptions of flying machines and perpetual motion devices.

The first sale of the models took place in 1925, resulting in the dispersal of more than one hundred thousand models among institutions and private collectors. In 1941, one such collector, the auctioneer O. Rundle Gilbert, purchased tens of thousands of models at a bankruptcy auction, saving them from being melted as scrap. He in turn sold around a thousand of these to Jack R. Crosby and Fred Lieberman in the early 1970s. In 1973 Crosby and Lieberman donated more than eight hundred pieces from this collection to the then Humanities Research Center at the University of Texas. Faced with space constraints of its own, the Harry Ransom Center transferred the collection to the Texas Memorial Museum between 1981 and 1988.

The models now serve the University of Texas as tools for teaching, scholarly exploration, and inspiration, and as concrete examples of the School of Law’s commitment to intellectual property law.—Elizabeth Haluska-Rausch
