 Braille read the Haüy books repeatedly , and he was equally attentive to the oral instruction offered by the school . He proved to be a highly proficient student and , after he had exhausted the school 's curriculum , he was immediately asked to remain as a teacher 's aide . By 1833 , he was elevated to a full professorship . For much of the rest of his life , Braille stayed at the Institute where he taught history , geometry , and algebra .
