This building was constructed in 1912 and originally known as the Farm Mechanics Building. On September 9 1938, it was heavily damaged by a fire caused by an experimental hop drier; it was reconstructed and expanded in 1939, and renamed the Agricultural Engineering Building. Portland architect John Bennes designed both the original building, and the 1939 expansion. In 1965, the Agricultural Engineering Building was renamed Gilmore Hall, in honor of William J. Gilmore, the head of the Farm Mechanics / Agricultural Engineering Department from 1915 to 1945.
