Built to accommodate a larger YMCA presence on campus during World War I, the Y-Hut was located from 1918 to 1926 in the location where the Memorial Union is today. It was removed to make way for the MU. The YWCA remained in Shepard Hall.
Linus Carl Pauling (1901-1994) graduated from Oregon Agricultural College in 1922 with a degree in Chemical Engineering. A giant of twentieth century science and a peace activist of international consequence, Pauling is Oregon State's most famous alumnus. He remains history's only recipient of two unshared Nobel Prizes (Chemistry, 1954; Peace, 1962).
