The editors of the Journal for General Philosophy of Science deeply regret to announce the death of Lutz Geldsetzer, one of the founding editors of JGPS. After a short illness he died on August 14, 2019, at Düsseldorf.

Lutz Geldsetzer was born on February 28, 1937 in Minden, Westphalia. He studied philosophy, sociology and law at the Johannes Gutenberg University in Mainz and received his doctorate from that university in 1961. After a stay at the Sorbonne in Paris and a position as research assistant in Mainz, he moved to Düsseldorf in 1963, where he qualified as a lecturer in 1967. From 1971 until his retirement in 2002, he was a Full Professor at the Heinrich Heine University in Düsseldorf, where he headed the research group of philosophy of science for many years.

In the early years of his academic career, Lutz Geldsetzer’s research focus was on the theory and history of the humanities. During his time as editor of this journal, he was primarily responsible for the hermeneutic tradition and the philosophy of the humanities more generally. Early on, however, he was also fascinated by the history and historiography of philosophy in general, which in his later years took up more and more of his time. He was a dedicated editor with a broad horizon, who attached great importance to the historiographical reflection of his works and who continually conquered new areas, including Asian philosophy. His numerous publicationsFootnote 1 cover many subfields of philosophy, including general philosophy of science, logic, hermeneutics, history of philosophy, philosophical anthropology, philosophy of arts and aesthetics as well as transcultural philosophy. He was a much sought-after scholar, with respect both to his research and his teaching: guest professorships took him, among other places, to France, Italy, the USA, and China.

Lutz Geldsetzer served as editor of this journal for almost 40 years, from 1970 to 2008. The current editors are deeply indebted to him for his work for the journal. His achievements as a researcher and teacher of philosophy will be remembered with great respect.
