Matilda effect
In 1944 the Nobel Prize in Chemistry was given to Otto Hahn as the sole recipient. Lise Meitner had worked with Hahn and had laid the theoretical foundations for nuclear fission (she coined the term "nuclear fission"). Meitner was not recognized by the Nobel Prize Committee, partly due to her gender and partly due to her persecuted Jewish identity in Nazi Germany. She was affected by the Law for the Restoration of the Professional Civil Service, which prohibited Jews from holding government-related positions, including in research. Initially, her Austrian citizenship shielded her from persecution, but she fled Germany after Hitler's annexation of Austria in 1938.
