The third significant German philosopher with whom I came into close contact was Ernst Mach, who had been professor at the University of Vienna....While active, he taught courses in the methodology of the inductive sciences and was known for siding with students during oral examinations. Because of a serious stroke, which in no way reduced his intellectual capacity, he had been forced to go into retirement in 1901. Since that time he lived in Vienna as a private scholar, but during his final years he settled in a village by Munich. He died in 1916.
