Mathematical Profile (Excerpt):
- Paul Bachmann is well known as the author of several textbooks in Number Theory and has a biography in this archive.
- Friedrich Bachmann attended the Gymnasium in Münster and, after graduating, he studied from 1927 in Berlin and Münster.
- After further work on logic, including starting to prepare the correspondence between Gottlob Frege and Bertrand Russell for publication, Bachmann turned to questions on geometry.
- Together with Karl-Heinrich Weise, Bachmann had a main share in rebuilding the 'Mathematisches Seminar' at Kiel after the war.
- Bachmann's lectures were highly liked and respected for their clarity and for being well structured.
- In this book Bachmann develops plane metric geometry by systematic use of reflections and the group of motions generated by them.
- Bachmann published an extended and updated second edition of this book in 1973.
- Later Bachmann dealt with an extension of his approach to so-called Hjelmslev groups, which is presented in the 1989, posthumously published, book Ebene Spiegelungsgeometrie.
- In 1970, in collaboration with Eckart Schmidt, Bachmann had published n-Ecke Ⓣ(n-gons) (an English translation with the title n-gons appeared in 1975).
