Dairoku Kikuchi

Baron Kikuchi Dairoku (菊池 大麓; 17 March 1855 – 19 August 1917) was a Japanese mathematician, educator, and education administrator during the Meiji era. After earning degrees in mathematics and physics from St John's College at the University of Cambridge, he became one of the first Japanese professors of mathematics at the University of Tokyo. Later in his life, he served as president of the University of Tokyo, Kyoto University, Gakushuin, and the Riken Institute.

Early life and family

Kikuchi was born in Edo (present-day Tokyo), as the second son of Mitsukuri Shūhei, a professor at Bansho Shirabesho, himself the adopted son of Mitsukuri Gempo, a Shogunate professor. The Mitsukuri family had distinguished themselves as scholars, and were at the centre of Japan's educational system in the Meiji era. His grandfather had been a student of Dutch studies ("rangaku").

Kikuchi Dairoku changed his surname from Mitsukuri to Kikuchi upon succeeding as the heir to his father's original family; the requisite legal procedures were completed in 1877.

Education

After attending the Bansho Shirabesho, the Shogunal institute for western studies, he was sent to Great Britain, in 1866, at age 11, the youngest of a group of Japanese sent by the Tokugawa shogunate to the University College School, on the advice of the then British foreign minister Edward Stanley, 15th Earl of Derby.

Kikuchi returned to England in 1870 and was the first Japanese student to graduate from the University of Cambridge (St. John's College) and the only one to graduate from the University of London in the 19th century. His specialisation was in physics and mathematics. In 1884 he attended the International Meridian Conference in Washington, D.C., and the master class of Kelvin in Baltimore.
