Paul Julius Moebius

Paul Julius Möbius (1853 – 1907)

Paul Julius Möbius (1853 – 1907) was a German neurologist.

Möbius specialised in neuroanatomy and neurological disorders but published on a wide variety of topics including thyroid dysfunction, gender determination and the inheritance of mental attributes

Through his studies of dysfunction and paralysis of the eye muscles, and in particular Morbus Basedow (Graves disease), he established increased activity of the thyroid gland as the cause of the disease and weakness of convergence, the so-called Möbius sign, as a diagnostic test
