In 1926 as part of a series of studies on professional education in the United States funded by the Carnegie Foundation for the Advancement of Teaching, Dr. William Gies published a landmark report, Dental Education in the United States and Canada, that established the importance of dentistry as a healing science and an essential component of higher education in the health professions. The report took five years to research and write and included lengthy descriptions and evaluations of the existing dental schools, each of which Dr. Gies visited.
