Angie Debo, Oklahoma Historian Extraordinaire 1890 - 1988.
My first day at the Society one of the archivists sat me down for an introductory chat. It was important to understand from the start of my work, he said, that the early history of Oklahoma was, as he put it, corrupt and venal. It was not Oklahoma! And the person we had to thank for having the courage to write the true history of her state, against concerted opposition from major political figures who wished to preserve the Boomer/Sooner myths, was Angie Debo.
Read this brief summary of her life -- http://www.unl.edu/plains/publications/resource/debo.shtml. Imagine what it must have been like for this remarkable woman, working tirelessly for years in the same dusty archive, piecing together the heartbreaking story of the Indian nations and individuals of Oklahoma and beyond.
The scrupulous and disciplined passion of her self-imposed calling animates every word she wrote in such books as And Still the Waters Run: The Betrayal of the Five Civilized Tribes, A History of the Indians of the United States, Geronimo: The Man, His Time, His Place, and more. Her work is accurately called the cornerstone of American Indian scholarship.
p.s. The Oklahoma State Capitol got its dome in 2002. A portrait of Debo hangs in the rotunda area. The Historical Society moved to brand-new quarters in the Oklahoma History Center in 2005.
