Julian Grobelny (16 February 1893 – 5 December 1944) was an activist in the Polish Socialist Party (PPS) from 1915, in the lead-up to Poland's return to independence. During the interwar period he was a social activist. After the German-Soviet invasion of Poland in 1939, and the ensuing Holocaust, he became President of Żegota (Council for Aid to Jews) active in the General Government territory of occupied Poland. The clandestine organization was named after a fictional character born on the exact day of its inception in 1942. Grobelny served as president of Żegota until the end of hostilities.
