Along with Conrad Grebel and Felix Manz, he was a co-founder of the Swiss Brethren in Zürich, and thereby one of the founders of Anabaptism.
He was educated at the University of Leipzig and served as a priest of the Roman Catholic Church until his conversion to evangelical Anabaptism.
Blaurock had evidently departed from the Catholic Church before he arrived in Zürich circa 1524, for he had already taken a wife.
On January 21, 1525, the despondent group held a secret meeting at the home of Felix Manz.
Arising from the prayer, George Blaurock asked Conrad Grebel to baptize him upon a confession of faith in Christ.
