A Century of Toledo Scale

Written by Timothy Messer-Kruse

Among the most recognized brand names of the twentieth century is Toledo Scale, a company whose headquarters and primary design and production facilities were located in its namesake. One of the greatest achievements of the Toledo's Attic Committee (especially its point man for collections, Ernest W. Weaver, Jr.) during 1998 was securing possession of the corporate papers of Toledo Scale from the Mettler Toledo Corporation. Along with many cases of documents, ledgers, photographs, and other archival materials, the Toledo Scale Collection includes a series of paintings by Georges LaChance of the skilled artisans of the company. In this exhibit, Toledo's Attic Virtual Museum presents a few of the items from this vast collection. Prepared by Timothy Messer-Kruse.
