A part of the novel I am currently working on features a court case presided over by a judge of African-American extraction. I understand that at the time, black people were second-class citizens in the South and in the Mid-West, thus such an occurrence wouldn't have happened there - am I right in guessing it was more plausible in New York? Were there black judges in America in the '40s?
EDIT: I searched Wikipedia but came up with nothing. Thank you to all who assisted me.
