Thomas Marshall Clark, teacher and college officer, son of Esther (D'Spain) and Joseph Addison Clark, was born at Midway, Texas, on January 7, 1856. The family moved to Fort Worth in 1867. In 1873 Thomas's brothers, Addison and Randolph Clark, settled at Thorp Spring in Hood County and established Add-Ran College, where Thomas was secretary-treasurer and teacher of music, dramatics, and languages. He married Alice Yantis in 1878, and they had one son. In 1894 the family moved to Portland, on Corpus Christi Bay, where Clark established Bay View College, a private school for girls. When the college was closed in 1917 he moved to Wichita Falls, where he taught until 1919, when he went to West Texas State Teachers College (now West Texas State University) at Canyon. He taught history and languages there until 1932. From 1934 to 1936 he taught at Cisco Junior College. After retiring in 1936 Clark lived at his home at Portland until his death, on April 21, 1943.
