Fritz Mauthner

He became editor of the ''Berliner Tageblatt'' in 1895, but is remembered mainly for his ''Beiträge zu einer Kritik der Sprache'' (''Contributions to a Critique of Language''), published in three parts in 1901 and 1902. Ludwig Wittgenstein took several of his ideas from Mauthner, and acknowledges him in his ''Tractatus Logico-Philosophicus'' (1922). Provided by Wikipedia
