Johann Friedrich Osiander (2 February 1787 in Kirchheim unter Teck – 10 February 1855) was an obstetrician at Göttingen, who published a prize essay in 1808 on nerves of the uterus titled Commentatio anatomico-physiologica, qua edisseretur uterum nervos habere, noting that he believed that nerves were present in the uterus but could not detect them.
In 1811 he became a privat-docent at Göttingen, also working as a general practitioner and obstetrician, and in 1815 was appointed an associate professor of medicine.
In 1817 he traveled to Vienna, where he met with Johann Lukas Boër (1751–1835); afterwards visiting Berlin, Jena and Halle (Saale).
However, following the death of his father, the government preferred Ludwig Julius Caspar Mende (1779–1832) as director of the Göttingen maternity hospital.
Therefore, the younger Osiander became a professor of medicine, later taking over the zoological and ethnographic department of the academic museum.
