Mr. Maddox was born on March 20, 1907 in Ballinger. His musical career began in Ballinger about 1921 when he learned to play a cornet he had obtained from a mail-order catalog. It was in the 1930's when Mr. Maddox graduated from Baylor University with a BBA degree.He began teaching in Ranger in 1923. When he went to Cisco in 1935, band was a part of the regular school program. His 1939 move to Mexia, a major step up in his career, permitted him to devote his teaching time solely to band work.

In 1946, the Odessa years began. Until 1959, Robert Maddox held the baton over the Odessa High Bronco Band, and in 1959 he became the first Coordinator of Music for the Ector County Independent School District, a position he held until retirement in 1973.
