Louis Harms

Georg Ludwig Detlef Theodor Harms (baptised as Ludwig, but called Louis during his life) (1808–1865) was a German Lutheran pastor who was nicknamed the "Reviver of the Heath" (''Erwecker der Heide''). One of the most significant Christian revivalists of the 19th century, he turned the little village of Hermannsburg on the Lüneburg Heath into the most important centre of revival in Lower Saxony.
