On September 20, 1725, he enrolled at the University of Leiden where he became a student of Herman Boerhaave, and a classmate of Albrecht von Haller. He graduated on 26 July 1726 presenting his dissertation titled "De morsu". He spent four years in Amsterdam working with the Dutch anatomist Frederik Ruysch. He returned to Königsberg on August 15, 1730. On September 23, 1741, he became professor of medicine at the Medical Faculty of the Königsberg College and a royal Prussian physician. Following the death of Melchior Philipp Hartmann, he took over his position and then became rector. Bohl is known as the sponsor of Immanuel Kant, whom he also financially supported during his time at the Collegium Fridericianum. Kant dedicated his first book, Thoughts on the True Estimation of Living Forces, to Bohl.
