It’s impossible to spend much time reading about the abolition and women’s suffrage movements in early 19th century America without running across the Grimké sisters. Sarah and Angelina Grimké were among the leading lights of both those civil rights movements prior to the Civil War, and I have long admired their courage and dedication to promoting social equality. It was only recently, however, that I learned that Sarah’s and Angelina’s nephews—the Grimké brothers—were among the leading lights of late 19th century and early 20th century intellectual and civil rights movements.
