Christoph Sauer (1695 – September 25, 1758) was the first German-language printer and publisher in North America.
Johann Christoph Sauer was born in 1695 in Ladenburg (near Heidelberg), the son of a Reformed pastor. He came to the County (Graftschaft) of Wittgenstein in central Germany as a child with his widowed mother some time between 1700-1710. He was a graduate of a German university, and studied medicine at the University of Halle. At the time, its rulers were tolerant of a variety of Pietists and other religious dissenters, most notably Alexander Mack, who would later found the Church of the Brethren in the United States. He married the widowed Maria Christina (born Gruber) in 1720. The family lived in the village of Schwarzenau, which now belongs to the town of Berleburg though had ties to Laasphe as well.
The family emigrated to Pennsylvania in 1724, settling in Germantown. Sauer worked as a tailor before moving in 1726 to Lancaster where he had a 50-acre (200,000 m2) farm. In 1731, Sower's wife, Maria Christina, joined Johann Conrad Beissel's Seventh Day Baptist community at Ephrata, the Ephrata Cloister. She was known in Ephrata as "Sister Marcella," and eventually became sub-prioress of the community, which was dedicated to celibacy. Maria Christina's decision disabled Sower's farming operation, and he moved with his son to Germantown where that same year he built a large dwelling for his residence.
In order to supply the needs of other German-speaking people in the colonies who were liberally educated, especially in theology, he obtained Bibles and religious works from Germany.
