In 1867, Willamette University founded the first medical school in the Pacific Northwest, the third such college west of St. Louis. The college was maintained in Salem from 1867 until 1913 except for the period 1878 to 1895, during which it operated in Portland. A medical school building erected at the northwest corner of the campus in 1905 served the school until 1913, when the college merged with The University of Oregon School of Medicine in Portland.
