Lucien Tesnière (] ; May 13, 1893 – December 6, 1954) was a prominent and influential French linguist.
 He was born in Mont-Saint-Aignan on May 13, 1893.
 As a professor in Strasbourg (1924), and later in Montpellier (1937), he published many papers and books on Slavic languages.

 He presented his theory in his book "Éléments de syntaxe structurale" (Elements of Structural Syntax), published posthumously in 1959.
 In the book he proposes a sophisticated formalization of syntactic structures, supported by many examples from a diversity of languages.
 Tesnière died in Montpellier on December 6, 1954.
