What would become known as the Prest-o-lite Battery Company, Inc., in this 1941 advertisement began as the Concentrated Acetylene Company, a business venture between James Allison, Carl Fisher, and P.C. Avery.  The business originated in 1906 from Avery’s idea to equip cars with nighttime driving lights by means of acetylene compressed into portable containers.  The Concentrated Acetylene Company was located at the corner of 28th and Pennsylvania Streets.
