"History of the United States" is a monumental synthesis of American History subsequently produced by Charles A. Beard and his wife, Mary R. Beard. This book covers a period from the beginning of American Colonization to the establishment of The League of Nations. Charles Austin Beard (1874-1948) was one of the most influential American historians 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, who he believed were motivated more by economics than by philosophical principles. Mary Ritter Beard (1876-1958) was an American historian and archivist, who played an important role in the women's suffrage movement and was a lifelong advocate of social justice through educational and activist roles in both the labor and woman's rights movements.
