This e-special issue of Theory, Culture & Society showcases work published in the journal by and about the late German sociologist Ulrich Beck (1944–2015). Beck became known as a pioneering and inventive thinker, continuously engaged in a quest to capture the essence of the modern age, whilst simultaneously wrestling with the upcoming horizons of the future. During his career, he was responsible for developing some of the defining sociological concepts of the late 20th and early 21st century, including risk, reflexive modernization, individualization and cosmopolitanism. He published many articles in Theory, Culture & Society, inspiring acolytes to mobilize his ideas and provoking critics to dispute them. Complementing articles written by Beck, this collection also includes critical commentaries, applications of his work, a selection of interviews and several reflective pieces which consider his legacy. The key aspiration of this special issue is to encourage contemplation on both the richness and the range of Ulrich Beck’s academic contribution. The contents stimulate reflection on the intricacies of Beck’s method of inquiry and flag up ways in which his work can influence the future trajectory of social theory.
