Henry Heusken

Hendrick Conrad Joannes Heusken was a Dutch-American interpreter for the first American consulate in Japan, established at Gyokusen-ji in Shimoda, Shizuoka in the late Bakumatsu period. He played an important role in the negotiations for the "Harris Treaty", which opened commercial relations between Japan and the United States, and his assassination caused a minor diplomatic crisis between Japan and the various Western powers.
