Évian Conference
Schorr concentrated mainly on scientific work, teaching, and social activities, rather than politics, but in 1935, the president of Poland Ignacy Mościcki named him Senator in the parliament. In his parliamentary speeches, along with articles in the Jewish press, such as "Nasz Przegląd" and "Chwila," Schorr expressed his concern about the growth of antisemitism in Poland and the passive conduct of the authorities in this regard. He led the Jewish immigration and colonial committee, which aimed to make possible the Jewish immigration from Poland to countries other than Palestine. He participated in the Évian Conference in France on the problem faced by 500,000 Jewish refugees from Germany and Austria with the advent of the Nazi regime and the "Anschluss" of Austria in 1938. The Évian Conference, held in Évian-les-Bains on the French shore of Lake Geneva, was convened at the initiative of US President Franklin D. Roosevelt, who invited European, American, and Australian delegates for an open discussion on organising the resettlement and immigration of those who experienced persecution on the basis of religion or race. Schorr was one of the key speakers in Évian and was highly involved as many Jews fled Germany for Poland. Golda Meir represented Palestine as an observer.
