On May 10, 2016, Thomas Luckmann passed away at his residence in Austria (Ossiacher See) at the age of 88 years. One of the most outstanding representatives of sociology of the past decades left us. An influential personality, his name is inextricably connected to the University of Konstanz and to the continuation of Alfred Schütz’s work on the “structures of the lifeworld”. Luckmann gained worldwide attention due to his numerous contributions to the foundation of phenomenological sociology, the sociology of religion in modern societies, and the analysis of communicative genres and the sociology of knowledge.
