Jack Sawtelle Blanton (December 7, 1927 - December 28, 2013) was an American oil industry executive, civic leader and philanthropist.
He was born in Shreveport, Louisiana, the son of William N. Blanton (June 23, 1890 – November 27, 1967) and Louise G. Wynn (September 21, 1898 – July 5, 1989). Blanton was raised in Houston, Texas, where his father was general manager of the chamber of commerce. After attending Lamar High School, Blanton earned a B.A. degree at University of Texas at Austin (UT) in 1947 with a double major in government and history, and an L.L.B. at UT Law School in 1950.
In 1950 Blanton began working for Eddy C. Scurlock at Scurlock Oil Company in the Division Order Department. He rose through the company ranks to become its president in 1958, and eventually CEO and chairman in 1983, a year after the company was sold to Ashland Oil. He retired from his position in 1988 to become the president of Eddy Refining Company, his final job.
Blanton was married three times. He married Laura Lee Scurlock (June 4, 1928 – August 6, 1999), daughter of Eddy C. Scurlock; the Laura Lee Blanton Building at Southern Methodist University is named for her. After her death, he married Lucinda B. Bailey (November 4, 1934 – March 2, 2002) on 14 November 2000. She also preceded Blanton in death; he and Virginia "Ginger" Nelson were married on November 30, 2002 (she survived his passing). He and his first wife had three children, Elizabeth Louise Blanton (born February 1, 1951); Jack Sawtelle Blanton, Jr. (born July 28, 1953); and Eddy Scurlock Blanton (born May 25, 1955).
