Susumu Tonegawa is a Japanese immunologist and molecular biologist who has made groundbreaking contributions to our understanding of the immune system.
Birth and Death Dates
-------------------------
Born on September 6, 1939, in Nagoya, Japan. As of this writing, he is still alive.
Nationality and Profession(s)
---------------------------------
Japanese national, Immunologist, Molecular Biologist
Early Life and Background
------------------------------
Susumu Tonegawa was born into a family of modest means. His father was an engineer, and his mother was a homemaker. Growing up in post-war Japan, Tonegawa developed a strong interest in science from an early age. He attended the prestigious Nagoya University, where he studied chemistry and graduated with a Bachelor's degree in 1962.
Major Accomplishments
-------------------------
Tonegawa's research focused on the immune system, particularly the structure of antibodies. In 1984, he discovered the gene segments that encode antibody diversity. This fundamental discovery revolutionized our understanding of how the immune system generates an immense variety of antibodies to fight off pathogens.
In 1987, Tonegawa was awarded the Nobel Prize in Physiology or Medicine for his work on immunoglobulin genes. He shared this honor with two other scientists: Baruj Benacerraf and Jean Dausset. This recognition catapulted Tonegawa into international prominence as a leading expert in immunology.
Notable Works or Actions
-----------------------------
Tonegawa's laboratory at the University of Geneva (now known as the Ecole Polytechnique Fédérale de Lausanne) became a hub for innovative research on antibody diversity. His team developed novel techniques to study gene expression and regulation, laying the groundwork for future breakthroughs in immunology.
Impact and Legacy
------------------------
Susumu Tonegawa's discovery of gene segments has far-reaching implications for our understanding of immune function. This knowledge has contributed significantly to:
The development of targeted therapies against cancer and autoimmune diseases.
Improved vaccine design, allowing for more effective protection against infectious diseases.
* Enhanced understanding of the molecular mechanisms underlying immune disorders.
Tonegawa's work has inspired generations of scientists to explore the intricacies of the immune system. His research continues to shape the field of immunology, driving advancements in medicine and public health.
Why They Are Widely Quoted or Remembered

Quotes by Susumu Tonegawa
The water bath has a platform which the rats learn to find because they don't like to get wet. Then you remove the platform. But you don't tell the rats.
When General Motors builds a car, they want to meet the specific needs of many customers. But if they custom-make each car, then it will not be economical.
Our study showed that the false memory and the genuine memory are based on very similar, almost identical, brain mechanisms. It is difficult for the false memory bearer to distinguish between them.
In 1981, after ten years in Basel, I returned to the United States to continue my research on the immune system at the Center for Cancer Research of the Massachusetts Institute of Technology where Director Salvador E. Luria provided me with an excellent laboratory.
Immunologists agreed that an individual vertebrate synthesizes many millions of structurally different forms of antibody molecules even before it encounters an antigen.
I decided to pursue graduate study in molecular biology and was accepted by Professor Itaru Watanabe's laboratory at the Institute for Virus Research at the University of Kyoto, one of a few laboratories in Japan where U.S.-trained molecular biologists were actively engaged in research.
I commuted to the prestigious Hibiya High School from my uncle's home in Tokyo. During the high school years, I developed an interest in chemistry, so upon graduation, I chose to take an entrance examination for the Department of Chemistry of the University of Kyoto, the old capital of Japan.
I became fascinated by the then-blossoming science of molecular biology when, in my senior year, I happened to read the papers by Francois Jacob and Jacques Monod on the operon theory.
Even under normal conditions, how we can distinguish various events, various experiences, and be able to reproduce it later is, of course, a very interesting question and, I think, one that we face in day to day life.
