Zygmunt Bauman (ˈbaʊmən; 19 November 1925 – 9 January 2017) was a Polish sociologist and philosopher. He was driven out of the Polish People's Republic during the 1968 Polish political crisis and forced to give up his Polish citizenship. He emigrated to Israel; three years later he moved to the United Kingdom. He resided in England from 1971, where he studied at the London School of Economics and became Professor of Sociology at the University of Leeds, later Emeritus. Bauman was a social theorist, writing on issues as diverse as modernity and the Holocaust, postmodern consumerism and liquid modernity.
Bauman was born to non-observant Polish Jewish family in Poznań, Second Polish Republic, in 1925. In 1939, when Poland was invaded by Nazi Germany and the Soviet Union, his family escaped eastwards into the USSR.
During World War II, Bauman enlisted in the Soviet-controlled First Polish Army, working as a political instructor. He took part in the Battle of Kolberg (1945) and the Battle of Berlin. In May 1945, he was awarded the Military Cross of Valour. After World War II he became one of the Polish Army's youngest majors.
According to the Polish Institute of National Remembrance, from 1945 to 1953 Bauman was a political officer in the Internal Security Corps (KBW), a military intelligence unit formed to combat the Ukrainian Insurgent Army and the remnants of the Polish Home Army. However, the nature and extent of his collaboration remain unknown, as well as the exact circumstances under which it was terminated.
In an interview with The Guardian, Bauman confirmed he had been a committed Communist during and after World War II and had never made a secret of it. He admitted that joining the military intelligence service at age 19 was a mistake although he had a "dull" desk job and did not remember informing on anyone. While serving in the Internal Security Corps, Bauman first studied sociology at the Warsaw Academy of Political and Social Science.
