David Rytz
David Rytz von Brugg (1 April 1801, in Bucheggberg – 25 March 1868, in Aarau) was a Swiss mathematician and teacher. Life Rytz von Brugg was son of a priest and studied mathematics at Göttingen and Leipzig. He had teaching positions at various cities, one of them 1835 until 1862 at Aarau, where he was ''„Professor der Mathematik an der Gewerbeschule zu Aarau“''.Alexander Ostermann, Gerhard Wanner: ''Geometry by Its History.'' 2012, S. 69 Merits Rytz von Brugg is famous for a geometrical method which is known as Rytz’s axis construction. This classical procedure retrieves the semi-axes of an Ellipse from any pair of conjugate diameters In geometry, two diameters of a conic section are said to be conjugate if each chord (geometry), chord parallel (geometry), parallel to one diameter is bisection, bisected by the other diameter. For example, two diameters of a circle are conjugate .... This method is known since 1845, when it was published within a paper by Leopo ...
