Friends of Jefferson sought to debunk the Hemings story as early as 1800, and most subsequent historians and biographers followed suit, finding the affair unthinkable based upon their view of Jefferson's life, character, and beliefs. Gordon-Reed responds to these critics by pointing out numerous errors and prejudices in their writings, ranging from inaccurate citations, to impossible time lines, to virtual exclusions of evidence—especially evidence concerning the Hemings family. She demonstrates how these scholars may have been misguided by their own biases and may even have tailored evidence to serve and preserve their opinions of Jefferson.
