Ellen Gleditsch (1879–1968) became Norway’s first authority on radioactivity and the country’s second female full professor. From her many years abroad—in Marie Curie’s laboratory in Paris and at Yale University in New Haven with Bertram Boltram—she became internationally acknowledged and developed an extensive personal and scientific network. In the Norwegian scientific community she was, however, less appreciated, and her appointment as a professor in 1929 caused controversy. Despite the recommendation of the expert committee, her predecessor and his allies spread the (...) view that Gleditsch was a diligent but outdated researcher with little scientific promise—a view that apparently persists in the Norwegian chemical community today. In addition to her scientific work, Gleditsch acquired political influence by joining the International Federation of University Women in 1920; she later became the president of both the Norwegian section and the worldwide organization. She worked in particular to establish scholarships enabling women to go abroad. I once worked with a learned man who was reputed to hate women. On one occasion he stated that the new collaborator was a rare exception. When he was asked why he said, “She does not scream.” I heard this several months later and have kept it as a great compliment; yes—the biggest in my scientific career. —Ellen Gleditsch. (shrink)
