Dr. William Williams Keen was United States' first brain surgeon, who once participated in a procedure removing a cancerous tumor from the jawbone of President Grover Cleveland.
His grandson, Dr. Walter Freeman, was famous for his practice of transorbital lobotomies. Thousands of mentally ill Americans, and some not mentally ill, underwent these operations at his hands, not too many decades ago.
Drs. Keen and Freeman are descendants of my Keen ancestors from Pennsylvania.
I'm... not sure how to feel about this. :)
