Young Klaproth devoted his energies in quite early life to the study of Asiatic languages, and published in 1802 his "Asiatisches Magazin" (Weimar 1802–1803). He was in consequence called to St. Petersburg and given an appointment in the academy there. In 1805 he was a member of Count Golovkin's embassy to China. On his return he was despatched by the academy to the Caucasus on an ethnographical and linguistic exploration (1807–1808), and was afterwards employed for several years in connection with the academy's Oriental publications. In 1812 he moved to Berlin.
