1845
Gauss spent 11 years managing and
keeping the Göttingen University “tidy”. This work gave him real effective
experience in economics and he began to make a living out of scrawny
investments and bonds issued by private companies. He also gave some classes to the
university’s students. Gauss’s last doctoral student was called Dedekind. Dedekind wrote
a fine description of his supervisor, giving a real inside on how Gauss
expressed himself and his ideas to others.
“... usually he sat in a comfortable attitude, looking down, slightly stooped, with hands folded above his lap. He spoke quite freely, very clearly, simply and plainly: but when he wanted to emphasize a new viewpoint ... then he lifted his head, turned to one of those sitting next to him, and gazed at him with his beautiful, penetrating blue eyes during the emphatic speech. ... If he proceeded from an explanation of principles to the development of mathematical formulas, then he got up, and in a stately very upright posture he wrote on a blackboard beside him in his peculiarly beautiful handwriting: he always succeeded through economy and deliberate arrangement in making do with a rather small space. For numerical examples, on whose careful completion he placed special value, he brought along the requisite data on little slips of paper.”
