Coral Horton Tullis, educator, historian, and long-time corresponding secretary of the Texas State Historical Association, the daughter of John Thomas and Collistia (Polk) Horton, was born on October 18, 1882, in Elmo, Kaufman County, Texas. Her mother was a third cousin of President James K. Polk. Coral graduated from Quanah High School in 1898 and Terrill School in Denton in 1901. She taught in the Travis County schools from 1901 to 1903 and in the Austin public schools from 1904 to 1906. In 1906 she was married to John Ledbetter Tullis, and they were the parents of four children. From 1912 to 1922 they lived in Lane County, Oregon, but returned to Austin in 1922. Mrs. Tullis entered the University of Texas, earning a B.A. in 1924, along with a Phi Beta Kappa key, and in 1927 she took an M.A. She became a member of the university's history department in 1924, and in 1959, at the time of her retirement from the faculty, she was an assistant professor of history. During most of her years on the University of Texas campus, Mrs. Tullis was identified with the work of the Texas State Historical Association. She was corresponding secretary from 1927 to 1942; in 1942 (with the death of Charles William Ramsdell, who had held the position of treasurer from 1907) the association combined the offices of corresponding secretary and treasurer; Mrs. Tullis was elected annually to that position from 1942 until her retirement in 1967. Historians had great respect for her knowledge of the association and its Southwestern Historical Quarterly, In 1937, when the association was forty years old, the editors of the Quarterly requested Mrs. Tullis to compile a list of all articles printed in the magazine up to that year. The July 1937 issue carried her compilation of "Publications of the Texas State Historical Association, July 1897, through April, 1937." At its seventy-first annual meeting in 1967, the association honored Mrs. Tullis at the time of her retirement, after forty years of service, with an inscribed silver tray. She died in Austin on June 22, 1967, and was buried in the family plot at Quanah. Beginning at the 1968 annual meeting of the Texas State Historical Association, the Coral Horton Tullis Memorial Award was presented annually to the person who in the previous year had made the greatest contribution to Texas history.
