Ruby Terrill Lomax (1886 – December 28, 1961) was an American educator and folklorist, who worked with her husband John A. Lomax to collect American folk songs, campaigned for women's education, and was Dean of Women at University of Texas at Austin.
She was born and raised in Denton, Texas, United States, just outside Dallas, Ruby Terrill earned degrees at state colleges, setting a record at the University of Texas at Austin for the highest grade average yet achieved by a woman at the university. Recognizing that education was her calling, she taught in rural and urban high schools and colleges in her home state, supporting herself while continuing her own studies. She worked toward a doctorate in classical languages by garnering a fellowship in Latin at the University of Texas for the year 1914–1915 and taking summer courses for four years at the University of Chicago and two years at Columbia University.
In 1925, Terrill received an M.A. in classical languages from Columbia University, with a major in Latin and a minor in Greek, and soon after accepted the position of dean of women and associate professor of classical languages at the University of Texas at Austin. During her tenure at the university, she kept active in a variety of local, national, and international societies. Ever popular with the students and involved with both the faculty and the community, she was renowned for her sense of humor and gentle consideration.
As her education and career indicate, Ruby Terrill was an accomplished and progressive woman in her time. In 1929, she joined with eleven other Texas women educators to found the Delta Kappa Gamma Society International, an honorary society dedicated to advancing the professional interests and position of women in education. She was nominated parliamentarian, guiding the society procedurally for its first four years, and she eventually held a number of other positions, including first vice-president (1933).
