Heinrich August Jäschke (17 May 1817 in Herrnhut – 24 September 1883) was a German Tibetologist missionary and Bible translator. From 1857 to 1868 he was missionary of the Herrnhuter Brüdergemeine (the Moravian Church or Moravian Brethren) in Kyelang, Lahaul District and Spiti in North India.

Jäschke has been called "the most distinguished linguist in the whole history of the Moravian Church" by James Hutton in his ''A History of the Moravian Missions'' (1923). Provided by Wikipedia
