Hertha Wambacher

Who was Hertha Wambacher?

Hertha Wambacher was an Austrian physicist. After having obtained the general certificate of education from the girls' high school run by the Association for the Extended Education of Women in 1922, she studied first chemistry, then physics at the University of Vienna.

Wambacher's dissertation at the 2nd Physics Institute was supervised by Marietta Blau, with whom Wambacher continued to collaborate also after her Ph. D. graduation in 1932. The cooperation of the two women referred to the photographic method of detecting ionizing particles. For their methodical studies at the Institute for Radium Research of the Austrian Academy of Sciences in Vienna, Blau and Wambacher received the Lieben Prize of the Austrian Academy of Sciences in 1937. Also in 1937, Blau and Wambacher jointly discovered "disintegration stars" in photographic plates that had been exposed to cosmic radiation at an altitude of 2300 m above sea level. These stars are the patterns of particle tracks from nuclear reactions of cosmic-ray particles with nuclei of the photographic emulsion.
