후쿠자와 유키치
Tsuda was born as the fourth son of a low ranking "samurai" of Sakura domain in Shimōsa (present day Sakura city, Chiba Prefecture). At the age of 15, he was sent to the domain's school, where he learned English and Dutch, and afterwards was sent to Edo, where he studied "rangaku." He was hired by the Tokugawa bakufu as an interpreter, and accompanied Fukuzawa Yukichi on a mission to purchase warships in the United States in 1867.
