Ottomar Rosenbach

Ottomar Rosenbach (1851 - 1907)

Ottomar Ernst Felix Rosenbach (1851 – 1907) was a German physician.

He published numerous works across a wide scope of medicine, including clinical signs, disease processes, novel laboratory methods in diagnosis, psychotherapy, heart disease pathophysiology, philosophy, and sociomedicine.

Controversially, Rosenbach opposed the bacteriology ideas, arguing that there was lacking evidence that microorganisms were part of the aetiology of certain diseases.

Dr Ottomar Rosenbach’s name is eponymous with Rosenbach sign of aortic regurgitation (1878), Rosenbach sign of autoimmune hyperthyroidism, Rosenbach-Semon Law (1880), and Rosenbach test (1880).
