Q: Question: What other roles did George Alexander play in his career? Passage 1:In 1903, the party split into Bolsheviks led by Vladimir Lenin and Mensheviks led by Julius Martov and Lunacharsky sided with the former. In 1907, he attended the International Socialist Congress, held in Stuttgart. When the Bolsheviks in turn split into Lenin's supporters and Alexander Bogdanov's followers in 1908, Lunacharsky supported his brother-in-law Bogdanov in setting up Vpered. Like many contemporary socialists (including Bogdanov), Lunacharsky was influenced by the empirio-criticism philosophy of Ernst Mach and Avenarius. Lenin opposed Machism as a form of subjective idealism and strongly criticised its proponents in his book Materialism and Empirio-criticism (1908). In 1909, Lunacharsky joined Bogdanov and Gorky at the latter's villa on the island of Capri, where they started a school for Russian socialist workers. In 1910, Bogdanov, Lunacharsky, Mikhail Pokrovsky and their supporters moved the school to Bologna, where they continued teaching classes through 1911. In 1913, Lunacharsky moved to Paris, where he started his own Circle of Proletarian Culture.
 Passage 2:Halleck's plan, finalized in January 1864, called for Banks to take 20,000 troops up from New Orleans to Alexandria, including the 47th Pennsylvania Infantry, the only regiment from the Keystone State to fight in this campaign, on a route up the Bayou Teche (in Louisiana, the term bayou is used to refer to a slow moving river or stream), where they would be met by 15,000 troops sent down from Major General William T. Sherman's forces in Vicksburg, Mississippi, and under the command of Brigadier General A.J. Smith. Smith's forces were available to Banks only until the end of April, when they would be sent back east where they were needed for other Union military actions. Banks would command this combined force of 35,000, which would be supported in its march up the Red River towards Shreveport by Union Navy Rear Admiral David Dixon Porter's fleet of gunboats. At the same time, 7,000 Union troops from the Department of Arkansas under the command of Major General Frederick Steele would be sent south from Arkansas to rendezvous with Banks in his attack on Shreveport, and to serve as the garrison for that city after its capture.
 Passage 3:The Prodigal Son is a best-selling novel by Hall Caine, published in November 1904 by Heinemann and translated into thirteen languages. It is set in a sheep-rearing community in rural Iceland, with scenes in London and the French Riviera. At the same time Caine adapted the novel into a play. The copyright performance was held at the Grand Theatre, Douglas, Isle of Man. American and British productions opened days apart in 1905, at the National Theatre in Washington, D. C. on 28 August, the New Amsterdam Theatre in New York City on 4 September and at the Theatre Royal, Drury Lane, London on 7 September, with George Alexander playing Oscar and Caine's sister Lilian playing Thora. After a long run at Drury Lane it was revived in 1907. In The Prodigal Son Magnus learns on his wedding day that his bride, Thora, is in love with his brother Oscar, a composer. She marries Oscar after Magnus releases her from the engagement. When Thora dies, a distraught Oscar places the only copies of his compositions in her coffin. Later he has her grave opened and his music retrieved. It was filmed in 1923. A.E. Coleby's 18,454 feet, nineteen reel film The Prodigal Son became the longest commercially made British film.
