Charles Beard

Charles Austin Beard was an American historian who wrote primarily during the first half of the 20th century. For a while, he was a history professor at Columbia University, but his influence came from hundreds of monographs, textbooks, and interpretive studies in both history and political science. His works included a radical re-evaluation of the Founding Fathers of the United States, whom he believed to be more motivated by economics than by philosophical principles. From Wikipedia
