VPI President T. Marshall Hahn, whose tenure ran from 1962 to 1974,[30] was responsible for many of the programs and policies that transformed VPI from a small, historically white, predominately male, military institute with a primary focus on undergraduate teaching into a major co-educational research university. The student body that had been approximately 5,682 in 1962 increased by roughly 1,000 students each year, new dormitories and academic buildings were constructed, faculty members were added – in 1966, for instance, more than 100 new professors joined the faculty – and research budgets were increased.[30] During Hahn's tenure, not only did the university graduate its first Rhodes Scholar, W.W. Lewis, Class of 1963,[31] the requirement for male students to participate in the Corps of Cadets for two years was dropped in 1964.
