Hertha Wambacher

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.

After Blau had to leave Austria in 1938, Hertha Wambacher continued working on the identification of particles from nuclear reactions of cosmic rays with the emulsion constituents.

In 1945, Wambacher who – according to her own words – had belonged to the NSDAP since 1934, was removed from the University of Vienna.
