Henry Adams is perhaps the most eclectic, accomplished, and important American writer of his time. His autobiography and modern classic The Education of Henry Adams was widely considered one of the best English-language nonfiction books of the 20th century. The last member of his distinguished family—after great-grandfather John Adams, and grandfather John Quincy Adams—to gain national attention, he is remembered today as an historian, a political commentator, and a memoirist.

Now, historian David Brown sheds light on the brilliant yet under-celebrated life of this major American intellectual. Adams not only lived through the Civil War and the Industrial Revolution but he met Abraham Lincoln, bowed before Queen Victoria, and counted powerful figures, including Secretary of State John Hay, Senator Henry Cabot Lodge, and President Theodore Roosevelt as friends and neighbors. His observations of these men and their policies in his private letters provide a penetrating assessment of Gilded Age America on the cusp of the modern era.
