Nikolaus Ludwig von Zinzendorf und Pottendorf, Imperial Count of Zinzendorf and Pottendorf, (May 26, 1700 - May 9, 1760), German religious and social reformer and bishop of the Moravian Church, was born at Dresden. Zinzendorf had a naturally alert and active mind, and an enthusiastic temperament that made his life one of ceaseless planning and executing. Like Martin Luther, he was often carried away by strong and vehement feelings, and he was easily upset both by sorrow and joy. He is commemorated as a hymnwriter and a renewer of the church by the Evangelical Lutheran Church in America on their Calendar of Saints on May 9.
