Masatoshi Koshiba (1926–2020)
Born 1926 CE, died 2020 CE.
Masatoshi Koshiba (小柴 昌俊, Koshiba Masatoshi; 19 September 1926 – 12 November 2020) was a Japanese physicist and one of the founders of neutrino astronomy. His work with the neutrino detectors Kamiokande and Super-Kamiokande was instrumental in detecting solar neutrinos, providing experimental evidence for the solar neutrino problem. Koshiba won the Nobel Prize in Physics in 2002, jointly with Raymond Davis Jr., "for pioneering contributions to astrophysics, in particular for the detection of cosmic neutrinos". Koshiba was the first Japanese Nobel laureate to hold two doctoral degrees. In addition, he was the second Japanese recipient of both the Nobel Prize and the Wolf Prize. His mentor, Sin-Itiro Tomonaga, and his student, Takaaki Kajita, were also Nobel Prize winners in Physics. He was a senior counselor at the International Center for Elementary Particle Physics (ICEPP) and professor at the University of Tokyo.
