Beschreibung Eines Ellipsograph

A superb monograph on the theory, construction and use of a mechanical drawing device to describe ellipses. The author, Georg Friedrich Parrot (1767 – 1852) was a German scientist, the first rector of the Imperial University of Dorpat (University of Tartu), being elected by the University Council consisting of all chaired professors. In this capacity, Parrot skillfully fought for the academic freedom and the self-government of the university, protecting her from the political pressure of Baltic German barons who had been given the right to autonomously govern in the Baltic provinces.
