Robert Lee Bobbitt was born near Hillsboro, Texas, the son of Joseph A. and Laura Duff Bobbitt. He graduated from North Texas Normal College in 1911, and from the University of Texas Law School in 1915. After opening a law practice in Laredo, Bobbitt married Mary B. Westbrook on April 20, 1918, while an officer in the 90th Infantry Division during World War I. Bobbitt was elected to the Texas Legislature in 1923, served three two-year terms, the last as Speaker of the House of Representatives, and was appointed Attorney General in 1929.
He returned to private practice in San Antonio in 1931, and served on the Board of Directors of the Texas College of Arts and Industries. In 1935, he was selected as an Associate Justice of the San Antonio Court of Civil Appeals, a post from which he resigned in 1937 to receive an appointment as the Chairman of the Texas Highway Commission. During Bobbitt's six-year term, the Texas Highway Department made great strides toward a goal of a connected system of paved roads in the state. In 1944, Bobbitt was a presidential elector, and, in 1958, was appointed to his last public service post, as a member of the Board of Regents of North Texas State College, his Alma Mater. (1974)
