Regarded as a titanic artistic and aesthetic achievement, the influential literary magazine The Dial published most of the great modernist writers, artists, and critics of its day. As publisher and editor of The Dial from 1920 to 1926, Scofield Thayer was gatekeeper and guide for the movement. His editorial curation introduced the ideas of literary modernism to America and gave American artists a new audience in Europe.

In The Tortured Life of Scofield Thayer James Dempsey looks beyond the public figure best known for publishing the work of William Butler Yeats, T. S. Eliot, William Carlos Williams, E.E. Cummings, and Marianne Moore to reveal a paradoxical man fraught with indecisions and insatiable appetites, and deeply conflicted about the artistic movement to which he was benefactor and patron. Thayer suffered from schizophrenia and faded from public life upon his resignation from The Dial. His struggle with mental illness and his controversial personal life led his guardians to prohibit anything of a personal nature from appearing in previous biographies. The story of Thayer's unmoored and peripatetic life, which in many ways mirrored the cosmopolitan rootlessness of modernism, has never been fully told until now.
