August Schleicher

August Schleicher (; 19 February 1821 – 6 December 1868) was a German linguist. Schleicher studied the Proto-Indo-European language and devised theories concerning historical linguistics. His great work was ''A Compendium of the Comparative Grammar of the Indo-European Languages'' in which he attempted to reconstruct the Proto-Indo-European language. To show how Indo-European might have looked, he created a short tale, Schleicher's fable, to exemplify the reconstructed vocabulary and aspects of Indo-European society inferred from it.
