Overview

  • The Nobel Assembly said it did not speak with Ramsdell until Tuesday morning in Sweden because he was completely out of contact when the award was announced.
  • Ramsdell learned of the prize when his wife's phone filled with messages during a stop in Montana after a multi-week hiking trip across Montana, Idaho and Wyoming.
  • He was described as very happy and surprised upon hearing the news, and he later said he felt grateful and humbled.
  • Ramsdell shares the award with Mary Brunkow and Shimon Sakaguchi for research on immune tolerance, including work on regulatory T cells that underpins advances against autoimmune disease.
  • Reuters noted previous notification snags for Nobel announcements, citing Bob Dylan's delayed response in 2016 and a 2011 medicine award revealed after a laureate had died.
