the college, a statue of him was erected in 1918 in front of modern-day Academic Plaza. Initially, women were permitted to attend classes only as "special students" but were not permitted to seek degrees. In 1893, Ethel Hudson, a daughter of one of the faculty, became the first woman to take classes; in 1899, her sisters Sophie and Mary Hudson did the same. Though not explicitly envisioned as such, over time it became a de facto all-male institution and led to a decades-long debate about the role of women at the college. In 1911, under pressure from the Texas Legislature, the college allowed women to attend classes during the summer semester. A.M.C. expanded its academic offerings with the establishment of the School of Veterinary Medicine in 1915. World Wars era Many Texas A&M alumni served during World War I and by 1918, 49% of all Aggies were in military service, a higher proportion than that of any other American college or university. In early September 1918, the entire senior class enlisted, and there were plans to send the younger students at staggered dates throughout the next year. Many of the seniors were fighting in France when the war ended two months later. More than 1,200 alumni served as commissioned officers. After the war, Texas A&M grew rapidly and became nationally recognized for its programs in agriculture, engineering, and military science. The first graduate school was organized in 1924 and the school awarded its first PhD in 1940. In 1925, Mary Evelyn Crawford Locke became the first female student to receive a diploma from Texas A&M but she was not allowed to participate in the graduation ceremony. The following month, the Board of Directors officially prohibited all women from enrolling. Many Texas A&M alumni served in the military during World War II; the college's educational and technical training resulted in 20,229 trained combat troops for U.S. military efforts. Of those, 14,123 alumni served as officers, more than any other school, and more than the combined total of the United States Naval Academy and the United States Military Academy. At the start of World War II, Texas A&M was selected as one of six engineering colleges to participate in the Electronics Training Program, which would train Navy personnel to maintain new radar systems. During the war, 29 Texas A&M graduates reached the rank of general. After the end of World War II,
