A member of the Beaver basketball squad during his undergraduate years, Valenti later served as freshman baseball coach, freshman basketball coach, head basketball coach and head tennis coach, spanning a time period from 1946-1970. He continued on as Assistant Athletic Director until retiring in 1982, and remained an enthusiastic ambassador for OSU until his death in 2014.
Richard Jeffrey Nichols was the librarian at Oregon Agricultural College from 1902 to 1908. A native Oregonian, Nichols was the first librarian not educated at OAC, earning his degree from Willamette University.
Charles Buren Mitchell (1886-1955) joined the faculty of Oregon Agricultural College in 1920 to head the new Department of Speech. As department head, he established and developed the dramatics and forensics programs at Oregon State. More than 200 plays were produced under his administration. Mitchell retired in 1952; the College Playhouse was renamed in his honor as the Mitchell Playhouse in 1961.
