Person: Gysel, Julius
Julius Gysel was a Swiss school-teacher with an interest in geometry.
Mathematical Profile (Excerpt):
- Gysel grew up in his hometown with his four siblings and attended elementary school there.
- After being awarded his Matura in 1869, Gysel studied mathematics at the Polytechnic until 1872.
- Subsequently, Gysel attended mathematics lectures at the University of Bern for a year, notably those by Georg Sidler and Ludwig Schläfli.
- Whilst writing his thesis, Gysel worked as a supply teacher for mathematics at the Kantonsschule in Schaffhausen from 1872-1874.
- Gysel taught mathematics in the classical track until his retirement in 1926.
- Despite all the educational reforms since Gysel's death, his observation about the popularity of the school subject mathematics still holds true today -- surely many of today's mathematics teachers would agree with him.
- Gysel greatly influenced the school not only as a teacher, but also in his capacity as headmaster in particular.
- Gysel's passion for physics experiments and technological progress (see paragraph below) is representative of his time.
- Gysel aka "Tschuli" was quite popular among his pupils, not only as a teacher, but also as headmaster.
- Throughout his life, Gysel educated himself further, both in his subjects and in educational matters.
- Gysel was also a keen member of the Naturforschende Gesellschaft Schaffhausen, his local Society for Natural Scientists, from 1876 onwards.
- Gysel became a member of the Deutsche Mathematiker-Vereinigung in 1897.
- The list of his publications comprises only seven items: apart from his doctoral thesis, Gysel published three papers on problems in geometry as part of his school's Osterprogramme: Beiträge zur analytischen Geometrie der Kurven und Flächen 2.
- On top of his school duties, Gysel took on a number of positions in various committees, which again reflect his interest in education and in technological progress.
- One of their sons, also called Julius (1881-1972), graduated as a mechanical engineer from the ETH in 1906 and worked for an electric power company.
Born 11 August 1851, Wilchingen (Schaffhausen canton), Switzerland. Died 23 August 1935, Schaffhausen, Switzerland.
