Question: What outspoken abolitionist and author of "An Appeal to the Coloured Citizens of the World" was also the father of one of the first black men to pass the Massachusetts bar?
Sentence (from "John Rock (abolitionist)"): John Stewart Rock (October 13, 1825 – December 3, 1866) was an American teacher, doctor, dentist, lawyer and abolitionist, historically associated with the coining of the term "black is beautiful" (thought to have originated from a speech he made in 1858, however historical records now indicate he never actually used the specific phrase on that day).
Relevant evidence: No
