Jean Baptiste Adoue, Sr., banker, was born in Aurignac, France, on October 24, 1846, the son of Jean Marie and Paule (Dorleac) Adoue. In 1861 he arrived in New Orleans with his younger brother. The trip from France to the United States took six months and was planned by the boys' older brother, who was already in the United States. The next year Adoue moved to Bryan, Texas. He subsequently operated a grocery store in Waco for a year before moving to Bremond, where he established a general store and private bank. In 1879 or 1880 he moved to Dallas and with several partners established a bank, Flippen, Adoue, and Lobit. Five years later he married Mittie Simpson, and the couple eventually had four children, including Jean Baptiste Adoue, Jr. Adoue became the president of his bank when it became the National Bank of Commerce in 1892. He continued as president until his death. In addition to his banking endeavors he was a partner in an investment firm and the director of two insurance companies. He was director and treasurer of the Old Dallas Club, a member of the City Club, a Mason, and a Shriner. He was the treasurer of the State Fair of Texas from 1899 until his death. He was appointed a French consular agent to settle the affairs of the La Réunion colony, a task he had just completed at the time of his death. He was a trustee of the Oak Cliff College for Young Ladies. On June 20, 1924, Adoue committed suicide in his Dallas home.
