Overview
- Ramsdell learned of the 2025 Nobel Prize in Physiology or Medicine during a camping trip when his wife briefly regained cellphone service and saw hundreds of messages.
- He had missed a pre-dawn call from the Nobel Committee and later spoke with secretary‑general Thomas Perlmann roughly 20 hours after the first attempt.
- The prize is shared with Mary E. Brunkow and Shimon Sakaguchi for work that explains how the immune system avoids attacking the body’s own tissues.
- Reporting notes that Brunkow initially dismissed the early call as spam, while Sakaguchi was reached later that morning as officials tried to contact the laureates.
- Ramsdell co‑founded Sonoma Biotherapeutics, which develops T cell therapies for autoimmune and inflammatory diseases, and the winners will receive 11 million Swedish crowns and gold medals.
