Steve Brown.

119 What a shock when we learned that Steven A. Brown, 52, succumbed to injuries resulting from a crash landing near the airport in Happy Valley-Goose Bay, Canada, on 14 December 2022. Steve, professor of chronobiology and sleep research at the Faculty of Medicine, University of Zürich, was an excellent scientist, a dear friend, a wonderful collaborator, and an incredibly courageous adventurer. His sudden death immediately reminded us of the Billy Joel song: Only the good die young. Steve owned a Piper PA-46 Malibu aircraft that he had to bring to Florida for an annual control and update. In company with his wife Patrycja Paruch, he then piloted his airplane to Nashua, NH, where they visited Steve’s mother. The trip was to continue to Nuuk, Greenland, with an intermediate stop in Goose Bay, Canada, where the tragic incident occurred. Patrycja, a highly successful physics professor at the University of Geneva and a great friend of ours, survived the crash. We would like to express our wishes of a full and prompt recovery and offer our sincere condolences to Patrycja. Our deepest sympathy goes to family members, friends, and colleagues of Steve.
