Mastered Chemistry and Mathematics.
Dr. Nicholas Sanderson, Lucasian Professor of Mathematics in the University of Cambridge, was one of the most remarkable men of his time. Born in 1682, at a small town in the County of York, he died at Cambridge in 1739, at the age of fifty-six years. He invented a table for teaching arithmetic palpably to the blind.
Dr. Henry Moyes professed the Newtonian philosophy, which he taught with considerable success as an itinerant lecturer. He was also a good chemist, a respectable mathematician, and a tolerable musician.
Herr Phefel, of Colmar, who lost his sight when very young, composed a great deal of poetry, consisting chiefly of fables, some of which were translated into French. Among the pupils of this learned blind man were Prince Schwartzenberg and Prince Eisemberg. He died at Colmar, 1809.
Weissemburgh, of Mannheim, became blind at the age of seven years. He wrote perfectly, and read with characters which he had imagined for his own use. He was an excellent geographer, and composed maps and globes, which he employed both in studying and teaching this science. He was the inventor of an arithmetical table differing but little from that of Sanderson.
