David J. Weber was among the first scholars to focus on the importance of the relationship between Mexico and the United States.
A dedicated Southern Methodist University history professor, he taught in the classroom until the end of the 2010 spring semester despite battling cancer.
Dr. Weber, 69, died Aug. 20 at a hospital in Gallup, N.M., near his summer home.
“As a historian, he was at least a generation ahead of his time in recognizing how entwined Mexico and the United States were and are,” said Benjamin Johnson, an SMU history professor.
