Konrad Steffen, who had been conducting research into climate change – notably in the Arctic and Antarctic – for over 40 years, died at the weekend following an accident in Greenland. As Director of the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL), he was regarded as one of the world’s leading authorities in this field.

“With Koni Steffen's death, we have lost a uniquely kind and committed colleague. Everyone in the ETH Domain is greatly saddened by this loss”, said ETH Board President Michael Hengartner. “Our thoughts are with his family and friends, to whom we send our heartfelt condolences”. 

Born in 1952, Konrad Steffen was a dual Swiss and American citizen. He had headed the WSL since 2012. Having studied natural sciences, he gained a doctorate from ETH Zurich in 1984. In 1990 he was appointed as Professor of Climatology at the University of Colorado in Boulder, USA, where he subsequently headed the Cooperative Institute for Research in Environmental Sciences (CIRES). As of 2012, he was also Professor for Climate and Cryosphere at ETH Zurich and at EPFL in Lausanne.
