Ray Owen

Ray D. Owen, Ph.D. (AAI '66), a pioneering immunologist who was the recipient of the AAI Excellence in Mentoring Award in 1999, died on September 21, 2014, at the age of 98. Owen's 1945 discovery of immunological tolerance in twin cattle was a building block for the experimental induction of tolerance through immune suppression and for early tissue grafting, which initiated the era of organ transplantation. An emeritus professor of biology at Caltech, Owen was remembered by many who benefitted from his generous and dedicated mentoring, including the authors of an AAI in memoriam appearing in the December 2014 issue of the AAI Newsletter. A remembrance published by Caltech is available here.
