Henry Adams (1838-1918), journalist, novelist, and historian, was the great-grandson of John Adams and grandson of John Quincy Adams, both presidents of the United States. A professor of medieval history at Harvard whose areas of research were wide-ranging, he was deeply interested in the evolution of democracy in the United States. While Adams is best remembered for his autobiography The Education of Henry Adams (1907), for which he was posthumously awarded a Pulitzer prize, his nine-volume history of the United States during the presidencies of Jefferson and Madison (1801-17), which was published 1889-91, has been hailed as one of the greatest historical works in English. Adams was an advocate of scientific history, and this monumental work adheres to its principles, considering social trends and circumstances rather than focusing on particular events. Volume 1 describes the first administration of Thomas Jefferson (1801-5).
