Popenoe is a Bethesda, Maryland inventor who created the Smartbolt (US patent #3,602,186), a bolt which indicates when the proper tension is achieved by providing a color-change indicator on the bolt head. The indicator is bright red when loose, and gradually darkens to black as the bolt is tightened. The indicator returns to red if the bolt once again becomes loose. Thus proper tension can be verified simply by visual inspection.
The collection documents inventor Chuck Popenoe through digital images, oral history, video documentation, and an Innovative Lives Presentation, and contains CDs, DVDs, digital audio tape (DAT), and a transcript of the oral history interview, conducted by Maggie Dennis and Alison Oswald.
