Edison held 49 cement patents


Patent for single-pour concrete house

This Saturday several OE members will be taking the Cement in the Lehigh Valley tour. The Intermountain Concrete Specialties website features information on Edison’s cement products that might be of interest to our group.

“Most people know Thomas Edison for the light bulb, but did you know the famous inventor also held 49 cement patents? An important part of concrete history, Edison’s patents included cement processing equipment, waterproofing cement paint, and even a mold for single-pour concrete construction. The visionary thinker imagined a future with concrete houses, concrete furniture, and even concrete pianos and refrigerators!”
