Hugo Liepmann

Hugo Karl Liepmann (April 9, 1863 - May 6, 1925) was a German neurologist and psychiatrist born in Berlin.

He initially studied chemistry and philosophy at the Universities of Freiburg and Leipzig, obtaining his doctorate in 1885. His interests later turned to medicine, and after completion of studies, worked as an assistant to Carl Wernicke in the psychiatric clinic at Breslau. In 1906 he became head physician at Dalldorf (Berlin-Wittenau), followed by an assignment as director of the Städtische Irrenanstalt zu Lichtenberg (Herzberge) in 1914.[1][2]

Liepmann is remembered for his pioneer work involving cerebral localization of function. From anatomical studies, he postulated that planned or commanded actions were controlled in the parietal lobe of the brain's dominant hemisphere, and not in the frontal lobe. He conducted extensive research of a disorder he called apraxia, a term that he introduced in 1900.[3] Apraxia is described as the inability to coordinate voluntary muscular movements that is symptomatic of some central nervous system disorders and injuries and not due to muscle weakness.[4] Liepmann believed that damage in the parietal lobe prevented activation of learned sequences of actions that are necessary to produce desired results on command. As a result of his studies, he divided apraxia into three types:
