Categories: Biographical notes
Ludwik Fleck (1896 – 1961) was a Polish / Israeli physician and biologist. He ran the bacteriology laboratory in Lvov until after the Gwerman invasion he was dismissed by the Nazis due to his Jewish identity. He was later incacerated in the Auschwitz concentration camp, but kept alive as his research into typhus was useful to the German military. He provided evidence for the Nurmeberg trials of Nazi war criminals. After the war he returned to senior posts in microbiology Poland, before emigrating to the new state of Israel.
Fleck developed a model of how sciencifitic thought develops that was influential on the work of Thomas Kuhn.
