It was first pronounced Herr-n-hut

Count Zinzendorf was born into a noble family (he was rich) but he still loved Jesus with his whole heart. As he grew older he became burdened for the oneness of Chistians and bought a village for the all kinds of Christians who were persecuted. At first, his village named Herrnhut had many different types of Christians who didn't believe the same things and didn't get along. Zinzendorf was obviously burdened for their oneness, so he preached and miraculously all of them repented!! They got along perfectly after that sermon!
Zinzendorf stressed the importance of Church meetings and soon corporate prayer turned into a burden of the people to spread the gospel throughout the earth. The Moravians were pioneers among modern missionaries.
The people in Herrnhut had so many miracles and prophecies that they soon got distracted from Christ - and only really cared about the results, not what those miracles and prophecies showed. Count Zinzendorf was thrown out of his village as a result of an investigation that occured, but he still ministered throughout Europe and America.
Near the end of his life, the Count experienced many troubles, a couple of which were finacial problems and opposition from religous leaders. He kept loving Jesus still however, and left a legacy of a Godly leader behind him.

Count Zinzendorf relates to IHOP's prophetic history in many ways. He founded a "missions base" for Christians. His goal was not religion but a real relationship with Christ. The coorperate prayer resulted in those Christians in Herrnhut spreading the gospel throughout the earth. The Count was an amazing leader and did some great things, and I think IHOP is like his Herrnhut in many ways.
