Norbert Wiener
Norbert Wiener was an American mathematician and philosopher. He was professor of mathematics at MIT.
Wiener was born in Columbia, Missouri, the first child of Leo Wiener and Bertha Kahn, Jews of Polish and German origin, respectively. Leo had educated Norbert at home until 1903, employing teaching methods of his own invention, except for a brief interlude when Norbert was seven years of age. Earning his living teaching German and Slavic languages, Leo read widely and accumulated a personal library from which the young Norbert benefited greatly. Leo also had ample ability in mathematics and tutored his son in the subject until he left home. In his autobiography, Norbert described his father as calm and patient, unless he failed to give a correct answer, at which his father would lose his temper.
