Who is David G. Burnet from Sam Houston and the American Southwest and what is their importance?

David G. Burnet, along with Sam Houston, was one of the fathers of Texas, and he was chosen to be interim president in the time when Texas had just set up a provisional government, and its future was greatly in doubt. Author Randolph B. Campbell paints Burnet as a somewhat short-tempered, short-sighted man, and he became a chief nemesis of Houston, both during the fight for Texas independence and later when Houston became president of Texas.
