Joseph Jules François Félix Babinski (Polish: Józef Julian Franciszek Feliks Babiński; 17 November 1857 – 29 October 1932) was a French-Polish professor of neurology.

Born in Paris, Babinski was the son of a Polish military officer, Aleksander Babiński (1824–1889), and his wife Henryka Wareńska Babińska (1819–1897),[1] who in 1848 fled Warsaw for Paris because of a Tsarist reign of terror instigated to stall Polish attempts at achieving independence and breaking the union between Congress Poland and the Russian Empire.

Free of teaching duties, while working at the Hôpital de la Pitié he was left with ample time to devote himself to clinical neurology.

With Jules Froment he published Hysteropithiatisme en Neurologie de Guerre (1917), which was translated into English in 1918 by J. D. Rolleston as Hysteria or Pithiatism, and Reflex Nervous Disorders in the Neurology of War.

[10] With Pierre Palau, Babinski, under the pseudonym "Olaf," wrote a disturbing play, Les détraquées, which premiered at the Deux-Masques theater in 1921.
