Building History

Originally built in 1921 as Margaret Snell Hall, a women's dorm, it became Extension Hall around 1958, and later Ballard Extension Hall. Frank L. Ballard (’16) graduated with a bachelor of science degree in agriculture from Oregon Agricultural College (now OSU). He served as the vice director of the Extension Service until he was appointed the president of Oregon State College (now OSU). After a short term as president, Ballard returned to the Extension Service, eventually becoming the Extension Service head from 1945 to 1961.
