Born in 1849, “Blind Tom” Wiggins found himself with three burdens and a gift: He was blind, he was mentally challenged, he was a slave, and he was a musical prodigy.

He was playing piano by ear at age 4, before he could speak. At 5 he composed a tune and found he could reproduce perfectly any piece from memory. His vocabulary was only about 100 words, and he spoke of himself in the third person (“Tom is pleased to meet you”), but in time he learned 7,000 piano pieces, mostly classics.

At age 8 a successful concert in Columbus, Ga., led to a tour. He played for James Buchanan and Mark Twain, accepting challenges to repeat original compositions to show there was no trickery. By age 16, he was touring the world.

He retired in 1883 but returned briefly for a series of New York concerts in 1904. He died in 1908.
