John A. Gable describes in detail the life and work of Hermann Hagedorn, historian, biographer, and long-time Director of the Roosevelt Memorial Association and its successor, the Theodore Roosevelt Association. Gable covers Hagedorn’s life as a child of German immigrants in Brooklyn, New York, his education and teaching at Harvard, and his early career as a writer and poet. He notes Hagedorn’s difficulties as a German-American during World War I and the start of his friendship with Theodore Roosevelt that would define his career. Gable traces Hagedorn’s leadership of the Roosevelt Memorial Association over nearly four decades, discusses his many publications on Roosevelt, and looks at his other writings, including a number of biographies and many works of poetry.
