Leah Sears is the first African-American WOMAN to serve as Georgia's Chief Justice. Her predecessor, Robert Benham, was the first African-American to hold that position.
Thanks to Jim Todd, a fellow University of Georgia alum of Justice Benham [and a dear friend and fellow University of Virginia alum of mine], for pointing out my error.
[Thanks to the wonders of blogging, I've already made the correction on the May 8 post.]
