Johann Otto Leonhard Heubner (January 21, 1843 – October 17, 1926) was a German internist and pediatrician who was a native of Mühltroff.
He was instrumental in improving infant mortality at the Charité, and introduced aseptic practices into the hospital environment.
[2] With Eduard Heinrich Henoch (1820–1910), he was among the first to use an antitoxin for diphtheria that had recently been developed by Emil von Behring (1854–1917).
He provided an early description of syphilitic endarteritis obliterans, a condition that is sometimes referred to as "Heubner's disease".
In 1999 the Otto Heubner Centrum für Kinder- und Jugendmedizin was founded at the University Hospital of the Charité-Berlin as a care center for young children and adolescents.
