Inquiring into Space-Time, the Human Mind, and Religion: The Life and Work of Adolf Grünbaum (1923–2018) Martin Carrier (Bielefeld University) and Gereon Wolters (University of Konstanz) 1. Adolf Grünbaum: A Twentieth-Century Biography Adolf Grünbaum was born in Cologne, Germany, on May 15, 1923, and died in Pittsburgh, Pennsylvania, on November 15, 2018. He has been one of the leading figures in twentieth-century philosophy of science. Grünbaum’s Jewish family managed to escape the Nazi terror and came to the US in 1938. He went to high school in New York City and moved to Wesleyan College to study mathematics, physics, and philosophy. Grünbaum became a US citizen in 1944 and still served in World War II, first in a military research unit and afterward in occupation service inter- rogating German academic prisoners. Grünbaum did his graduate work at Yale with a dissertation on space-time philosophy. In 1950, he got his first academic appointment at Lehigh-University in Bethlehem, PA. Ten years later he moved to the University of Pittsburgh to become the Andrew- Mellon Professor in Philosophy. In Pittsburgh, he established the then new Center for Philosophy of Science, rebuilt the Department of Philosophy, and was involved in founding the Department of History and Philosophy of Science (Grünbaum 2009, 56). The Center has evolved into one of the focal areas of philosophy of science around the globe. It enables external scholars to stay in Pitts- burgh for up to a year and has thereby contributed to the pursuit and completion of an immense number of philosophical projects. It has also catalyzed innumerable highly productive philosophi- cal exchanges, not only among the fellows, but also between fellows and Pitt faculty. In the past 60 years, the Pittsburgh Center has grown into a hotspot of international philosophical debate and interaction. Moreover, the early appointments made by Grünbaum (among them Nicholas Rescher and Larry Laudan (Grünbaum 2009, 56)) proved to be highly fruitful and started to transform the Departments of Philosophy and History and Philosophy of Science into leading institutions of philosophical research and teaching in the world. Grünbaum was highly honored by the philosophical community. He served several times as President of the American Philosophical Association (Eastern Division) and the Philosophy of Science Association and was a member of many high-ranking Academies. Among other awards, he received the Humboldt Research Award in 1985 and honorary doctorates from the universities of Konstanz and Cologne. In 1989, he was conferred the “Master Scholar and Professor Award” from the University of Pittsburgh. Grünbaum was celebrated by no less than three Festschrift vol- umes, Physics, Philosophy and Psychoanalysis: Essays in Honor of Adolf Grünbaum (1983), Phil-
