Emil Osann (May 25, 1787 – January 11, 1842) was a German physician and physiologist from Weimar.
[1] He studied medicine in Jena and Göttingen, and later worked an assistant in a Berlin polyclinic founded by his uncle, Christoph Wilhelm Hufeland (1762–1836).
In 1826 he became a full professor of Heilmittellehre (medical instruction), and in 1833 became director of the aforementioned clinic.
Osann is remembered for his work on the effects of mineral springs from a physical and medical standpoint.
Among his writings was a two-volume work on European mineral spas, titled Physikalisch-medicinische Darstellung der bekannten Heilquellen der vorzüglichsten Länder Europas.
