“I’d heard so many stories growing up about how my famous ancestor had discovered how glaciers moved,” Marian explained. “It wasn’t until my thirties that I learned from a sibling that he had problematic views about race. I’m ashamed to say that I did not pursue learning anything more—until I read about your lawsuit.” — Tamara Lanier, From These Roots, 871
