Obituary: Susumu Tonegawa, Japan’s first Nobel prizewinner in physiology or medicine

Nature NewsIndependentCenter18 hr. ago

Susumu Tonegawa, a pioneering Japanese neuroscientist and immunologist, passed away at age 86. He is celebrated for transforming understanding of learning and memory and for discovering the genetic basis of antibody diversity, which earned him the 1987 Nobel Prize in Physiology or Medicine—making him the first Japanese recipient. Born in 1939 in Nagoya, Japan, Tonegawa faced challenges during his academic career, including a PhD thesis he described as 'not particularly proud of.' Despite this, he became a postdoctoral researcher at the Salk Institute under Renato Dulbecco, who influenced his shift toward immunology. His groundbreaking research on B-cell gene rearrangement revolutionized immunology, while his work on memory mechanisms contributed significantly to neuroscience.
