On October 14, 1960, Presidential candidate John F. Kennedy put out the idea of what became the Peace Corps on the steps of Michigan Union. Lyndon B. Johnson's speech about his Great Society program also occurred at UM. Also during the 1960s, UM saw many protests by student groups. On March 24, 1965, a group of UM faculty members and 3,000 students held the nation's first ever faculty-led "teach-in" to protest against American policy in Southeast Asia. Because of a series of sit-ins in 1966 by "Voice"–the campus political party of Students for a Democratic Society–UM's administration banned sit-ins. This led 1,500 students to have another one-hour sit-in the LSA Building, which then housed the administrative offices. Former UM student and important architect Alden B. Dow designed the current Fleming Administration Building, which was completed in 1968. The building's plans were drawn in the early 1960s, before student activism created a concern for safety. Nevertheless, the Fleming Building's narrow windows, all located above the first floor, and castle-like outside led to a campus rumor that it was made to be riot-proof. Dow denied the rumors, saying the small windows were made to be use less energy.
