Korean War did not disrupt class graduation schedules. More than half of the Army leadership during the war was composed of West Point graduates. The Class of 1950, which graduated only two weeks prior to the war's outbreak, suffered some of the heaviest casualties of any 20th century class and became known sourly as "the class the crosses fell on." A total of 157 alumni perished in the conflict. Garrison H. Davidson became superintendent in 1956 and instituted several reforms that included refining the admissions process, changing the core curriculum to include electives, and increasing the academic degree standards for academy instructors. The 1960s saw the size of the Corps expand to 4,400 cadets while the barracks and academic support structure grew proportionally. West Point was not immune to the social upheaval of American society during the Vietnam War. The first woman joined the faculty of the all-male institution amidst controversy in 1968. West Point granted its first honorable discharge in 1971 to an African-American West Point cadet, Cornelius M. Cooper, of California, who applied for conscientious objector status in 1969. The academy struggled to fill its incoming classes as its graduates led troops in Southeast Asia, where 333 graduates died. Modern era Following the 1973 end of American involvement in Vietnam, the strain and stigma of earlier social unrest dissolved and West Point enjoyed surging enrollments. On 20 May 1975, an amendment to the Defense Authorization Bill of 1976 opening the service academies to women was approved by the House of Representatives, 303–96. The Senate followed suit on 6 June. President Ford signed the bill on 7 October 1975. West Point admitted its first 119 female cadets in 1976. Also in 1976, physics professor James H. Stith became the first tenured African American Professor. In 1979, Cadet, later General, Vincent K. Brooks became the first African American to lead the Corp of Cadets. Kristin Baker, ten years later, became the first female First Captain (a depiction of her is now on display in the Museum), the highest ranking senior cadet at the academy in 1989. Six other women have been appointed as First Captain: Grace H. Chung in 2003, Stephanie Hightower in 2005, Lindsey Danilack in 2013, Simone Askew in 2017, Reilly McGinnis in 2020, and Lauren Drysdale in 2022. Simone Askew was the first African American woman to lead the Corps. In the 21st century, women comprise approximately
