Regula Rytz
Regula Rytz (born 2 March 1962) is a Swiss historian and politician of the Green Party of Switzerland. She was a member of the National Council from 2011 to 2022. From 2012 to 2016, she was the co-president of the Green Party of Switzerland. She was the party president from 2016 to 2020. Early life, education and research Regula Rytz was born in Thun, Canton of Bern to Gisela Rytz-Flören, a musician, and Rudolf Rytz, an architect. She graduated as teacher (Swiss ''Lehrpatent'') at the Thun seminary, and worked from 1983 to 1989 as teacher on public elementary school level (''Volksschule''). Rytz studied history at the University of Bern and graduated (''Lizentiat'') in history, sociology and constitutional law in 1997. Her coop-programs included projects for the educational department (''Erziehungsdirektion'') of the canton of Bern from 1990 to 1992, and assistance work for Professor Richard Bäumlin at the constitutional law seminary (''Staatsrechtliches Seminar'') in 1992 ...

Rytz's Construction
The Rytz’s axis construction is a basic method of descriptive geometry to find the axes, the semi-major axis and semi-minor axis and the vertices of an ellipse, starting from two conjugated half-diameters. If the center and the semi axis of an ellipse are determined the ellipse can be drawn using an ellipsograph or by hand (see ellipse). Rytz’s construction is a classical construction of Euclidean geometry, in which only compass and ruler A ruler, sometimes called a rule, line gauge, or scale, is a device used in geometry and technical drawing, as well as the engineering and construction industries, to measure distances or draw straight lines. Variants Rulers have long ... are allowed as aids. The design is named after its inventor David Rytz of Brugg (1801–1868). Conjugate diameters appear always if a circle or an ellipse is projected parallelly (the rays are parallel) as images of orthogonal diameters of a circle (see second diagram) or as images of t ...

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 ...
