Fritz Hans Schweingruber
Fritz Schweingruber was first a primary school teacher and organist. Until 1965 he taught for nine years at multi-class schools in Emmental. Afterwards he studied botany, zoology, geology as well as prehistory and early history at the University of Bern and then wood biology at the ETH Zurich. An encounter with the Austrian botanist Bruno Huber sparked his interest in dendrochronology. In 1972 he graduated in systematic plant sociology.
After teaching biology at Gymnasium Köniz high school near Bern and at the private school "Dr. Feusi", he started in 1971, at the Swiss Federal Institute for Forest, Snow and Landscape Research WSL in Birmensdorf. There he set up the dendrochronology research group. In 1976 he was appointed as an associate professor at the University of Basel with a Habilitation on "Prehistoric Wood".
Research and worksEdit
At WSL, Fritz Schweingruber built the Northern Hemisphere dendroclimatological data network in collaboration with Keith Briffa from the University of East Anglia's Climatic Research Unit in Norwich, Eugen Vaganov Siberian Federal University in Krasnoyarsk and Stepan Shiyatov Ural Federal University in Ekaterinburg.
He organized expeditions to Western Europe, USA, Canada and Siberia. He educated students of the universities of Basel. Zurich, Bern, Stuttgart, Grenoble, Marseille, Tehran and Abakan (Russia). He initiated the "International dendroecological fieldweeks" (from 1986) and the "International Course on Wood Anatomy and Tree-Ring Ecology" (from 2001) and led the latter until 2019.
After his retirement in 2001, he pursued his research as a guest researcher at the Swiss Federal Research Institute WSL, with a focus on the taxonomic-anatomical-dendrochronological analysis of herbs and dwarf shrubs. One of his most important projects was the dating and anatomy of high mountain plants in the Alps and the Himalayas.
His publications in English include the textbooks Trees and wood in dendrochronology (1993), Tree rings and environment. Dendroecology (1996), Wood structure and environment (2007) and The Plant Stem (2018).
