Horace L. Traubel was an American essayist, poet, magazine publisher, and author. Traubel was closely associated with the Arts and Crafts movement in the United States and published a monthly literary magazine called The Conservator from 1890 until the time of his death. Although a poet of note in his own right, Traubel is best remembered as the literary executor and biographer of his friend, poet Walt Whitman, about whom he compiled nine volumes entitled Walt Whitman in Camden.
