Delta Omicron International Music Fraternity was founded on September 6, 1909 at the
Cincinnati Conservatory of Music by three undergraduate students: Hazel Wilson, Lorena Creamer, and Mabel Dunn. Additional charter members included Mae Chenoweth, Grace Hudson, and Adah H. Appell. The Articles of Incorporation were signed by the charter members on December 8, 1909 and filed in the office of the Secretary of State of Ohio.
