[Hans Steinert: 100 years of myotonic dystrophy].

This study includes for the first time detailed biographical facts about Hans Steinert (1875-1911), who in 1909 first described myotonic dystrophy (Steinert's disease) as an independent syndrome. Of utmost importance are Steinert's years at the medical hospital of Leipzig University, where in 1901 he became the assistant of his mentor Heinrich Curschmann (1846-1910). Shortly after being appointed Extraordinary Professor there, Steinert died at the age of 36. As early as 1912 Hans Curschmann (1875-1950) fully recognized the importance of Steinert's pioneering work. Referring to key passages in his 1909 investigation, this study demonstrates how, on the basis of precise observation, subtle neurologic examination, and great clinical experience, Steinert succeeded in identifying a syndrome that to this day plays an important role in neurologic practice.
