Hantaro Nagaoka

Hantaro Nagaoka was a Japanese physicist and a pioneer of Japanese physics during the Meiji period.

Nagaoka was born in Nagasaki, Japan, and educated at Tokyo University. After graduating with a degree in physics in 1887, Nagaoka worked with a visiting Scottish physicist, Cargill Gilston Knott, on early problems in magnetism, namely magnetostriction in liquid nickel. In 1893, Nagaoka traveled to Europe, where he continued his education at the universities of Berlin, Munich, and Vienna, including courses with James Clerk Maxwell on Saturns rings and Ludwig Boltzmann and his Kinetic Theory of Gases, two influences which would be reflected in Nagaokas later work. Nagaoka also attended, in 1900, the First International Congress of Physicists in Paris, where he heard Marie Curie lecture on radioactivity, an event that aroused Nagaokas interest in atomic physics. Nagaoka returned to Japan in 1901 and served as professor of physics at Tokyo University until 1925. After his retirement from Tokyo University, Nagaoka was appointed a head scientist at RIKEN, and also served as the first preside
