Max Lewandowsky

Max Lewandowsky (28 June 1876 – 4 April 1918) was a German neurologist, who was a native of Berlin, born into a Jewish family.

In 1902 he obtained his post-graduate qualification for physiology, and in 1904, received training in clinical neurology and psychiatry under Karl Bonhoeffer and Franz Nissl at the University of Heidelberg.

Lewandowsky coined the term blood–brain barrier in 1900, referring to the hypothesized semipermeable membrane which separated the human central nervous system from the rest of the body's vasculature, and which prevented the entry of certain compounds from entering the brain when injected into the bloodstream.

[5] In 1908, Lewandowsky and Stadelmann published the first report of an individual with calculation impairment due to brain damage (acalculia; the term would later be introduced by Salomon Eberhard Henschen in 1925).

[6] Beginning in 1910 he, together with Alois Alzheimer, edited the journal Zeitschrift für die gesamte Neurologie und Psychiatrie.
