Near the beginning of his first American lecture tour, Irish poet and playwright William Butler Yeats lectured on "The Intellectual Revival in Ireland." Yeats had arrived in America on November 11, and the lecture, one of four he had prepared for the country-wide tour, was that which he gave at Carnegie Hall on January 3, 1904, before a large Irish-American crowd and which he told his colleague Lady Augusta Gregory, was "my big lecture, the most important of the whole lot."

Yeats visited Vassar again, reading from his poems and speaking about them in May 1920.
