A Hungarian traveller and philologist, born in Koros, Transylvania; in the hope of tracing the origin of the Magyar race, set out for the East in 1820, and after much hardship by the way arrived in Thibet, where, under great privations, though aided by the English Government, he devoted himself to the study of the Thibetan language; in 1831 settled in Calcutta, where he compiled his Thibetan Grammar and Dictionary, and catalogued the Thibetan works in the library of the Asiatic Society; died at Darjeeling just as he was setting out for fresh discoveries (1784-1836).
