Karl Deisseroth's Nobel Prize win captured in family video

Karl Deisseroth, a 54-year-old Stanford neuroscientist, won the 2026 Nobel Prize in Medicine, sharing it with Peter Hegemann and Georg Nagel for developing optogenetics. A video captured his children's joyful reactions when he told them the news. The Nobel committee called from Stockholm at 12:27 AM California time, and Deisseroth first informed his mother before telling his children. His daughters Sophie, 10, and Emma, 13, screamed with joy and hugged him, while his 16-year-old son Hudson took a moment to process the news. Despite the international recognition and constant phone calls, Deisseroth quickly returned to his daily routine, preparing his children's school lunches. His 18-year-old son Alexander, a Stanford student, cycled home to celebrate with the family after learning the news.
