Johann Gottfried Zeller (5 January 1656 - 7 April 1734) was a German physician and medical writer.
He was born in Lienzingen, a hamlet in Mühlacker in the Duchy of Württemberg. His parents wished for him a career as a religious minister, but he chose to study medicine at the University of Tübingen. He then traveled through France, Holland, and Germany in furtherance of a doctorate. In 1684, he obtained a post with the Count of Oettingen. He returned to mainly teach at Tübingen. He traveled in 1716 to Vienna to attend to the pregnancy of the Austrian empress. [1]
