Four people who got knocked in the head and became acquired savants

A pianist, a geometer, an artist and a sculptor. The latter, Alonzo Clemons, “was 3 years old when he suffered a severe fall. To this day, in his late fifties, Clemons still retains an IQ of no more than 50, and he can neither read nor write.” Clemons’ works, though, have sold for as much as $45,000.
