Alumnus Homer Maris earned an M.S. degree in Agriculture from Oregon Agricultural College in 1918. In 1914, Maris began composing the words to a song that he felt would gather the spirit of Oregon Agricultural College, which became Carry Me Back, the College's alma mater. In 1918, Maris dedicated the piece to "Mother Kidder", the much-loved College librarian. Maris died in 1933 in a bicycle accident.
The Homer Maris Collection consists of materials pertaining to Homer Maris and the Oregon State University alma mater, Carry Me Back, written and composed by Maris. Of especial note are letters from Ida A. ("Mother") Kidder to Maris, to whom the alma mater is dedicated. The collection also includes annotated manuscript copies of Carry Me Back, documents pertaining to its copyright, correspondence, an obituary for Maris written by E.T. Reed, a 1920-21 Oregon Agricultural College student handbook, and three photographs. The photographs are an image of the Trysting Tree (ca. 1918), a portrait photograph of Ida A. Kidder (ca. 1915), and a portrait photograph of Homer Maris (ca. 1925).
