Louis Schneider (born Ludwig Wilhelm Schneider: April 29, 1805 – December 16, 1878) was a German actor and author.
Schneider was born in Berlin, the son of George Abraham Schneider (1770–1839). At an early age he was engaged at the Royal Theatre, Berlin, where he soon rose to play leading comedy parts. His reputation as a comedian grew with his success in such roles as Zierl in the Einfahrt vom Lande, Peter in the Kapellmeister von Venedig, Schikaneder in the Schuuspieidirektor and Basileo in Figaro's Hochzeit, and he became the favourite of Berlin.
In 1845 he was appointed head of the Royal opera in Berlin. But his bold patriotic couplets and impromptus during the revolutionary year 1848 necessitated his retirement, and thereafter he translated and adapted for the stage Mozart's Cosi fan tutti; published, under the pseudonym “L. W. Both,” Das Buhnenrepertoire des Auslandes; and founded, as a result of his experiences as a soldier in the Danish war of 1849, the periodical Der Soldatenfreund.
He also wrote Geschichte der Oper und des Opernhauses in Berlin (1845–1852). Soon after his retirement he was appointed reader to Frederick William IV of Prussia, and subsequently he received the title of Geheimen Hofrat. He continued to enjoy the favour of the court, and, as correspondent of the Staatsanzeiger, was attached to the headquarters staff of the Prussian army during the campaign of 1866; and, by special invitation, accompanied the emperor William during the war of 1870. Schneider also wrote a novel, Das böse Glück, and several volumes of reminiscences: König Wilhelm (1869), Kaiser Wilhelm, 1867–1871 (1875). He died at Potsdam.
