Described as good-natured and unassuming, she has devoted years of research to some reprehensible characters, such as slave-owner James Henry Hammond. She also studied Mary Chestnut , a Southern elitist who excoriated slaves and insulted a white woman in North Carolina who protected her from Yankee invaders.
"Sometimes I couldn't resist using those, probably because they weren't entirely representative but were such an extreme that they did have that startling effect that reminds you who these people were," Faust said in the magazine article, "and that they are not you."
I'm not sure how studying reprehensible characters parallels contradictions in Faust's life—I'm not sure Sacchetti even establishes that there are contradictions in Faust's life—but never mind. The piece is an interesting look at Faust's scholarship.
