Hans Thiersch was born on May 16, 1935 in Recklinghausen, Germany. His work became particularly influential since the 1970s, when he applied the concept of lifeworld orientation to social pedagogy. Indeed, Thiersch can be considered one of the representatives of a critical social pedagogy. Since his retirement in 2002, he has been a professor emeritus of Education and Social Pedagogy at the University of Tübingen. He has also co-edited the handbook of social work / social pedagogy. Professor Thiersch has published extensively on a variety of topics related to education, social work, youth welfare, residential care, morality and justice. However, because most of his publications are in German, his work is not well known outside of Germany. On a rainy evening of October 2013 in Frankfurt, I had the opportunity to have a conversation with Professor Thiersch.
