Woolsey Hall is the primary auditorium at Yale University, located on the campus' Hewitt Quadrangle in New Haven, Connecticut. It was built as part of the Bicentennial Buildings complex that includes the Memorial Rotunda and the University Commons, designed by the firm Carrère and Hastings for the Yale bicentennial celebration in 1901. With approximately 2,650 seats, it is the university's largest auditorium and hosts concerts, performances, and university ceremonies including the annual freshman convocation, senior baccalaureate, and presidential inaugurations. The building is named for Theodore Dwight Woolsey, President of Yale from 1846 through 1871.
During the 19th century, Yale became one of the largest higher education institutions in the world, establishing seven graduate and professional schools in addition to the undergraduate college founded in 1701. Although Yale was nominally organized as a university in 1887, its constituent schools remained mostly independent of the university administration, and they lacked any shared facilities. In 1896, as one of several initiatives to unify the new university, Yale President Timothy Dwight V proposed the construction of a central dining hall and auditorium, for which the university would need to raise $1.5 to $2 million.
The task of construction fell to the administration of Arthur Twining Hadley, who became president 1899, two years before the university bicentennial. The position of the buildings was selected as a central node between the Old Campus of Yale College and the Sheffield Scientific School, positioning the new university buildings as separate from the dominant College and partial to no school in particular.
Succeeding Battell Chapel as the university's largest assembly space, the new hall was the university's first secular auditorium, coinciding with Hadley's appointment as the first non-ordained person to lead the university. In 1910, a seat on the first balcony was made extra large to accommodate Yale's ultimate "big man on campus," trustee and alumnus William Howard Taft.
