The Alma Mater of a Nation was used to refer to William & Mary, starting in the late 1960s.
The booklet Alma mater of a nation : a bicentennial sampler for the College of William & Mary was probably published in 1975. William & Mary President Davis Y. Paschall used the phrase in a speech to a joint meeting of the appropriations committees of the General Assembly of Virginia in 1968. The phrase was also used by Mills Godwin, Governor of Virginia, in a Report on the Commission on Constitutional Revision at William & Mary on January 11, 1969.
While Alma Mater of a Nation might still be used by some, Alma Mater of the Nation is preferred (2016, News & Media Team).
