Costa Rican President Óscar Arias Sánchez lectured on the Oregon State University campus on October 28, 1992 as the eleventh Ava Helen Pauling Memorial Lecturer for World Peace. The Ava Helen Pauling Lectureship for World Peace was jointly established in 1982 by Dr. Linus Pauling and the OSU College of Liberal Arts in memory of Mrs. Pauling's multi-decade commitment to issues of peace and civil liberties. In 1995 the Lectureship was renamed to include Linus Pauling, who had died in August of the previous year.
