Some mistakes in that.
It lists Daniel Hale Williams as the first man to perform open heart surgery, but he was just one among many to attempt it. The first successful surgery on the heart itself, performed without any complications, was by a German doctor.
Also a black man did not invent the penicl sharpener, let alone as let as 1897! They ahd electric sharpeners in 1917! The real inventor of the penicl sharpener was french, and done it decades before 1897.
