Nicolaus Zinzendorf

Nikolaus Ludwig, Reichsgraf von Zinzendorf und Pottendorf was a German religious and social reformer, bishop of the Moravian Church, founder of the Herrnhuter Brüdergemeine, Christian mission pioneer and a major figure of 18th-century Protestantism.
Born in Dresden, Zinzendorf was often influenced by strong and vehement feelings, and he was easily moved both by sorrow and joy. Called Ludwig or Brother Ludwig by his intimates, he was a natural orator, and though his dress was simple his personal appearance gave an impression of distinction and force.
He was notable for providing shelter for German-speaking Moravian exiles at Herrnhut, an effort that was influenced by Pietist ideas from the Lutheran faith he was brought up in.
Zinzendorf was critical of slavery, and played a role in starting the Protestant mission movement by supporting two determined Moravian missionaries Johann Leonhard Dober and David Nitschmann to go to the Danish colony of Saint Thomas to minister to the enslaved population there.
