Theodore Roosevelt (1858–1919) was America's most published president with an incredible output of writing including forty books, over a thousand articles, and countless speeches and letters. Collected here in one volume are examples of Roosevelt’s voluminous writings over a dazzling array of topics. Organized by general categories, readers can sample writings on subjects as varied as the environment, the danger of professional sports; the famous charge of San Juan Hill, and Roosevelt’s passion for literary criticism. From addresses and presidential messages on public policy and national ideals, to biography, to travel writing, to ecological concerns, to writings on hunting, to international politics and history, Roosevelt’s talents and achievements as a writer went far beyond what we now expect of our public leaders. Roosevelt’s legacy as one of the first progressive American politicians, his concerns about environmentalism, his internationalism, and his unflinching belief in the American character and destiny uncannily speak to the issues of our own day and can be found in the pages of this representative and judicious anthology of his work.
