Upon retiring to Charlotte County in 2016, author Ted Ehmann was curious why after over twenty-five years of researching and visiting the Indian mounds of the Hopewell and Mississippian cultures of North America, there was not one mention of the Calusa and the mound building cultures in Charlotte Harbor and the entire south Florida Region. He claims, the Calusa and their neighbors have received very little archaeological investigations. Ehmann argues that the evidence reveals that the mound-building epoch in south Florida and the hunter-gathering societies responsible constitute a unique cultural epoch spanning twenty-five centuries, and is of global importance. Ehmann applies new models and connects the archaeological record to an earlier epoch in Louisiana, the latter epochs of the Hopewell and Mississippian mound builders, and the research by archaeologists outside of Florida.
He has a Master of Teaching degree and a B.A. degree , with a minor in Social Science and Anthropology College of New Jersey and studied for two years at the Philadelphia College of Art.
