Szacki was born in Warsaw in 1929. After World War II, worked for the Polish Telephone Authority, first as a locksmith, later in a desk job. In 1948, he began to study sociology at the University of Warsaw. Incidentally, his was the last class to graduate before sociology was declared a "bourgeois" discipline and the sociological departments of Polish universities were closed in 1952. Szacki himself was sent to work in the Wrocław-based train wagon factory Pafawag. In 1956, when the sociological department in Warsaw re-opened, Szacki returned there to obtain a Ph.D. degree. He wrote his thesis at the "Institute for the Education of Research Staff" ', which was attached to the Central Committee of the Polish United Workers' Party and was soon afterwards renamed to "Institute for Social Sciences" ', whose director at the time was Bronisław Baczko. Szacki completed his habilitation at the department of philosophy in 1965. He was appointed "extraordinary professor" in 1973 and "ordinary professor" in 1987, the highest rank in Polish academe. In the meantime, Szacki held various administrative positions at the University of Warsaw, including Vice-Dean of the Department of Social Sciences, Dean of the Department of Philosophy and Sociology, and director of the Institute for the History of Social Thought within the Institute of Sociology. Szacki retired from the university in 1999, but has been teaching at the private university-level Warsaw School of Social Sciences and Humanities since 2003. Szacki lectured and researched at several universities and institutions worldwide, including the New School for Social Research, the Collège de France, the University of Minnesota, the University of Oxford. From 1972 to 1976, Szacki was the president of the Polish Sociological Association, and held numerous further administrative positions, including in the Polish Academy of Sciences. From 1974 to 1991, he was editor-in-chief of the Polish Sociology Bulletin. Szacki is perhaps most noted for his monumental Historia myśli socjologicznej. Written in Minneapolis and Oxford and originally published in English in 1979, it failed to make a strong impact on international sociology, but remains a popular textbook among Polish teachers and students of sociology until this day. The updated edition of 2002 was awarded with the Prize of the Foundation for Polish Science', colloquially dubbed the "Polish Nobel Prize", in 2003 In the 1970s, Szacki began to maintain contacts with oppositional circles, although he never became an active figure in politics. In 1978, he participated in the informal discussion group Doświadczenie i Przyszłość, which brought together pro- and anti-government intellectuals. In 1991, Szacki co-founded the Solidarność Pracy, a short-lived social-democratic party formed by left-wing Solidarity members, which merged with the Labour Union' the following year. In 1998, he prefaced a book about the Gdańsk-based milieu of Polish liberals edited by the politician Donald Tusk. In 1994, Szacki published a book on Liberalism after communism, which was translated into English and other languages and received favourable reviews in the West. In it, Szacki addresses the challenges faced by liberal democracy in an environment shaped by decades of communism and earlier non-democratic governments - a topic that has occupied much of Szacki's academic publications and popular essays in the general press. Szacki also translated several classic works from English and French into Polish: Some English-language writings by Florian Znaniecki, a pioneering Polish sociologist, as well as Émile Durkheim's classic work Les Règles de la méthode sociologique, Jean-Pierre Vernant's Les origines de la pensée grecque and Marcel Mauss's Sociologie et anthropologie. In 2004, Szacki was honoured as a Righteous among the nations. As a teenager during World War II, Szacki had helped his mother Barbara Szacka hide and support a pregnant Jewish woman named Irena Hollender, who had escaped from the Warsaw Ghetto. In Nazi-occupied Poland, hiding Jews was an offence punishable by death. Szacki was married to fellow sociologist Barbara Szacka. He died on 25 October 2016.
