Ettore Majorana (1906—1938): Eine Bestandsaufnahme 64 Jahre nach seinem Verschwinden

Ettore Majorana probably belongs to the most mysterious and most fascinating personalities of the recent physics history. Majoranas work shows also nowadays more than 60 years after its appearance an amazingly fresh reference to present physics problems. A short representation of Ettore Majoranas life and scientific work will be given in this article.     

Isolde Hausser (7. 12. 1889-5. 10. 1951), Technische Physikerin und Wissenschaftlerin am Kaiser-Wilhelm-/Max-Planck-Institut für Medizinische Forschung,Heidelberg

Historical sociobiographic accounts on members of the scientific and technical professions in the years of the Weimar Republic and after, are as yet scarce. This applies notably to women in the scientific community. Having formally been admitted to academic studies at German Universities only in 1908, their claims of wanting to apply their newly gained knowledge and to pursue academic careers were still not unquestioned by society. The social and cognitive integration of “the female” in male dominated science organisation, especially in the natural sciences and their kin fields in industry, remains problematic to-day. Isolde Hausser, daughter of the ambitious but little succesful inventor-entrepreneur Hermann Ganswindt, took her doctoral degree in physics at Berlin University in 1914, then worked as head of a group at a “Telefunken” laboratory for vacuum tubes till 1929, before she became research scientist at the Kaiser Wilhelm Institute for Medical Research, Heidelberg. There she worked on photoerythemaes and the formation of pigment and discovered the specific action of longwave ultraviolet. She contributed important results to our knowledge on the constitution and the behaviour of organic compounds by modern physical methods. She died of cancer on 5th October, 1951.
