Matemáticos ciegos

The history of mathematics includes a number of blind mathematicians. One of the greatest mathematicians ever, Leonhard Euler (1707–1783), was blind for the last seventeen years of his life. His eyesight problems began because of severe eyestrain that developed while he did cartographic work as director of the geography section of the St. Petersburg Academy of Science. He had trouble with his right eye starting when he was thirty-one years old, and he was almost entirely blind by age fiftynine. Euler was one of the most prolific mathematicians of all time, having produced around 850 works. Amazingly, half of his output came after his blindness. He was aided by his prodigious memory and by the assistance he received from two of his sons and from other members of the St. Petersburg Academy.
