Raymond Charles Vietzen (September 5, 1907 - October 1, 1995) was an American automobile dealer, artifact collector, and amateur archaeologist. As prolific author and artist from Elyria, Ohio, he wrote and illustrated numerous articles, books, and chapters in edited volumes on the history and prehistory of North America winning him many honors—chief among them the title of "Colonel." Col. Vietzen is probably best known for establishing the Indian Ridge Museum in 1930 and for founding the Archaeological Society of Ohio (formerly the Ohio Indian Relic Collectors Society), whereby he presided as its editor, president, secretary, and treasurer from 1941 to 1980. Most of his publications are dedicated to the excavations that he led at many famous archaeological sites in Illinois, Kentucky, Ohio
