History of the Jews in Poland Polish Jews who gained international recognition are Moses Schorr, Ludwik Zamenhof (the creator of Esperanto), Georges Charpak, Samuel Eilenberg, Emanuel Ringelblum, and Artur Rubinstein, just to name a few from the long list. The term "genocide" was coined by Rafał Lemkin (1900–1959), a Polish-Jewish legal scholar. Leonid Hurwicz was awarded the 2007 Nobel Prize in Economics. The YIVO (Jidiszer Wissenszaftlecher Institute) Scientific Institute was based in Wilno before transferring to New York during the war. In Warsaw, important centers of Judaic scholarship, such the Main Judaic Library and the Institute of Judaic Studies were located, along with numerous Talmudic Schools
Ludwik Fleck Ludwik Fleck Ludwik Fleck (11 July 1896 – 5 June 1961) was a Polish and Israeli physician and biologist who did important work in epidemic typhus in Lwów, Poland, with Rudolf Weigl and in the 1930s developed the concepts of the ""Denkstil"" ("thought style") and the ""Denkkollektiv"" ("thought collective"). The concept of the "thought collective" defined by him is important in the philosophy of science and in logology (the "science of science"), helping to explain how scientific ideas change over time, much as in Thomas Kuhn's later notion of the "paradigm shift" and in Michel Foucault's concept of the "episteme".
