BORN TODAY: In Lemberg, Austria-Hungary (soon to be at the centre of the Polish-Ukrainian war, lasting until 1919, later taken by the Soviet Red Army, and now Lviv in Ukraine) – Andrzej Mostowski, “Polish mathematician…perhaps best remembered for his Mostowski collapse lemma. He became an accountant after the German invasion of Poland but continued working in the underground Warsaw University. After the Warsaw uprising of 1944 the Nazis tried to put him in a concentration camp. With the help of some Polish nurses he escaped to a hospital, choosing to take bread with him rather than his notebook containing his research. Some of this research he reconstructed after the War, however much of it remained lost.” [Wikipedia].
