"John Lockhart Coffey² - A native of Texas, but a resident of Oklahoma throughout practically all of his life, Mr. Coffey was educated in the schools and colleges of this State. Beginning to teach, when he was still a boy himself, at the age of sixteen years, he has devoted his life to that profession since then and in the various positions held by him has met with great success. This is more to his credit, because he has held such responsible positions as high school principal, superintendent of schools, and member of the faculties of University of Oklahoma and of the Oklahoma Agricultural and Mechanical College, at an age when most teachers are only beginning their careers. Since 1927 he has been president of the Cameron State School of Agriculture at Lawton, and in this position, too, he has bet with great success and has done excellent work. He is considered today one of the ablest men in educational work in Oklahoma and there is no doubt that he will accomplish even greater things in the years to come.
"John Lockhart Coffey was born in Alexander, Texas, February 4, 1898, a son of George and Julia (Lockhart) Coffey. Having come to Oklahoma in his childhood, he received his early education in the grade school at Sentinel. The family having removed later to the central part of Washita County, Mr. Coffey attended the rural school known as the Port and Spring Creek School. He finished his grammar school education at Spring Creek and then attended the Sentinel High School, after which he he commenced his career as a teacher. However, he continued his own education in later years and, in 1919, graduated from the Weatherford State Nornal School, at that time a junior college. Still later he continued his studies at the University of Oklahoma where he was graduated with the degree of Bachelor of Arts in 1921. In 1925 he received the degree of Master of Science from the Oklahoma Agricultural and Mechanical College, Stillwater. All of his educational work has been done in the State of Oklahoma, his first position having been that of high school principal at Carter, which position he held during 1914-15. Next he taught mathematics at the Junior High School at Broken Arrow, during 1915-1916, and then served as superintendent of schools at Bigheart during 1916-18. During the summer of 1918 he taught in the training department of the Weatherford Normal School and then spent two terms as superintendent of schools at Tyrone, 1918-1919. In 1919 and during 1920 he was connected with the University of Oklahoma in its high school department, and then again served as superintendent of schools, this time at Devol, during 1921-1922. In 1922 he became a member of the faculty at the Oklahoma Agricultural and Mechanical College at Stillwater, remaining with this institution until 1927. At first, during 1922-24, he was head of the department of secondary correspondence, and then, during 1925-27, he was professor of history.
"Since 1927 he has been president of the Cameron State School of Agriculture at Lawton, Comanche County. This school is now a junior college authorized by the State Legislature. [I have omitted the details about the college.]
"During the World War Mr. Coffey was a student member of the Student's Army Training Corps at the Weatherford State Normal School. He is now a second lieutenant in the Reserve Officers' Training Corps. In politics he is a supporter of the Democratic party."John Lockhart Coffey was also the author the The Five Civilized Tribes and Their Influence in Oklahoma History, Oklahoma A&M College Press, 1925.
