About Johann Nathanael Lieberkühn
- Johann Nathanael Lieberkühn (5 September 1711, Berlin – 7 October 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.
- Besides his physiological work, Lieberkühn was most known for his preparation of medical specimens—these were still presented up to the nineteenth century, especially in Moscow, as masterpieces.
- His specimens were prepared primarily with injections of wax-containing fluids into body cavities, creating relatively durable shapes.
- The Crypts of Lieberkühn (intestinal glands) are named for him; he first described these in detail in De fabrica et actione vollorum intestinorum tenuium hominis, in 1745.
- Beyond this, Lieberkühn produced optical instruments, further developing the light microscope, which he had seen for the first time in Amsterdam.
- His custom microscopes for studying blood vessels were called "Wundergläser", ‘wonder-glasses’ by his contemporaries.
- In 1755, Lieberkühn was elected a foreign member of the Royal Swedish Academy of Sciences.
