The Education of Henry Adams

The Education of Henry Adams

I stumbled upon the remarkable autobiography of Henry Adams by accident while reading a history of the end of the 19th century. When Adams’ autobiography was published after his death in 1918, it became a best seller and won the Pulitzer Prize. Adams is remarkable for his ability to speak to us more than 90 years later with a message that is both relevant and moving.
