Rudolf Brefin, ca.1885

Rudolf Brefin (born August 23, 1847 in Basel , † December 1, 1892 in Schopfheim ) was a Swiss physicist and mathematics teacher .

The son of a master baker, born in Basel in 1847, studied mathematics and physics (with Hermann Kinkelin , Eduard Hagenbach-Bischoff ) as well as mineralogy and philosophy from 1865 to 1868 after attending the humanistic grammar school in Basel . He then spent one semester each in Heidelberg (with Heinrich Weber , Otto Hesse , Gustav Robert Kirchhoff , Robert Wilhelm Bunsen and Hermann Kopp ) and Berlin (with Karl Weierstraß , Ernst Eduard Kummer , Leopold Kronecker , Georg Hermann Quincke and Heinrich Gustav Magnus ).

Back in Basel, Brefin taught at a grammar school and did his doctorate in 1871 under Hagenbach-Bischoff ( From the diffraction of light ). From 1872 to 1876 he was the main teacher at the canton school in Aarau , then for three years at the Benderschen Institute in Weinheim , after which he became the rector of the high school in Schopfheim . Brefin held this office until his death at the age of 45.

In 1883 he became the first chairman of the newly founded Schopfheim branch of the Black Forest Association , which in 1892 decided to build the observation tower on the Hohen Möhr . In 1885 he founded (together with Pastor Eberlin) a chess club in Schopfheim. Brefin married Bertha Friederike Boehringer in 1883; they had seven children.
