Johann Nathanael Lieberkühn

Johann Nathanael Lieberkühn (September 5, 1711, Berlin - October 7. 1756, Berlin) was a German physician. His middle name is sometimes misspelled Nathaniel.

Lieberkühn studied theology initially, and then moved to physics, in particular mechanics. It was only after this that he commenced medicine. In 1739 he moved to Leiden, in the Netherlands, and then a year later to London and Paris. Following this he returned to Berlin as a member of the Collegium medico-chirurgicum, the body charged with improving the teaching and science of medicine in the Holy Roman Empire, making mathematical and optical instruments and working as a professor and medical doctor.
