Rolf Hassler (1914-1984) was a German pathologist who made important discoveries on the pathophisiology and treatment of Parkinson's disease (PD).
In 1938 he published that autopsy of PD patients showed that while the striatum and globus pallidus were mostly unaffected, the main affected structure was the substantia nigra pars reticulata, which loosed many neurons and also held abundant Lewy bodies. Such findings confirmed Konstantin Tretiakoff theories, who in 1919 had reported that the substantia nigra was the main cerebral structure affected.
Hassler later was the director of the Max-Planck-Institut für Hirnforschung at Frankfurt am Main where he continued his studies on PD, becoming a pioneer in surgery for tremor.
