Johann Gottfried von Berger (November 11, 1659 – October 2, 1736) was a German physician and writer on physiology who was an early follower of the iatromechanical explanation of human organ functioning.
He became a professor of medicine at the University of Wittenberg and a court physician to King August of Poland.
Meeting in Rome in 1693, Berger suddenly left the city without notice, soon after Baglivi had lent him a number of manuscript pages from a planned work on reconstructive surgery.
Although Baglivi feared that Berger would plagiarise it, historiographical investigations have never revealed any evidence of publication of the missing manuscript pages in any form.
Why the pages were apparently removed from Rome, and how the dispute was settled is unknown, but by 1698 the two physicians were corresponding and on good terms.
