Manisha Sinha is the author of The Slave's Cause: A History of Abolition. After presenting to the National Endowment for the Humanities Abolition and the Underground Railroad program, I was able to spend some time with her. What was intended to be a 20-minute interview ultimately expanded to 35 minutes, and we just scratched the surface of her astounding research. This is the first of a series of at least seven interviews.
