Problem: Background: Richard was born on 2 October 1452 at Fotheringhay Castle, the twelfth of thirteen children of Richard Plantagenet, 3rd Duke of York and Cecily Neville at the beginning of what has traditionally been labelled the "Wars of the Roses", a period of "three or four decades of political instability and periodic open civil war in the second half of the fifteenth century", between supporters of Richard's father (a potential claimant to the throne of King Henry VI from birth)--"Yorkists"--in opposition to the regime of Henry VI and his wife, Margaret of Anjou, and those loyal to the crown ("Lancastrians"). When his father and the Nevilles were forced to flee to Ludlow in 1459, Richard and his older brother, George (later Duke of Clarence), were placed in the custody of the Duchess of Buckingham, and the Archbishop of Canterbury. When his father and elder brother Edmund, Earl of Rutland, were killed at the Battle of Wakefield on 30 December 1460, Richard, who was eight years old, and George were sent by his mother, the Duchess of York, to the Low Countries. They returned to England following the defeat of the Lancastrians at the Battle of Towton and participated in the coronation of Richard's eldest brother as King Edward IV in June 1461.
Context: Apart from Shakespeare, Richard appears in many other works of literature. Two other plays of the Elizabethan era predated Shakespeare's work. The Latin-language drama Richardus Tertius (first known performance in 1580) by Thomas Legge is believed to be the first history play written in England. The anonymous play The True Tragedy of Richard III (c. 1590), performed in the same decade as Shakespeare's work, was probably an influence on Shakespeare. Neither of the two plays places any emphasis on Richard's physical appearance, though the True Tragedy briefly mentions that he is "A man ill shaped, crooked backed, lame armed" adding that he is "valiantly minded, but tyrannous in authority". Both portray him as a man motivated by personal ambition, who uses everyone around him to get his way. Ben Jonson is also known to have written a play Richard Crookback in 1602, but it was never published and nothing is known about its portrayal of the king.  Marjorie Bowen's 1929 novel Dickon set the trend for pro-Ricardian literature. Particularly influential was The Daughter of Time (1951) by Josephine Tey, in which a modern detective concludes that Richard III is innocent in the death of the Princes. Other novelists such as Valerie Anand in the novel Crown of Roses (1989) have also offered alternative versions to the theory that he murdered them. Sharon Kay Penman, in her historical novel The Sunne in Splendour, attributes the death of the Princes to the Duke of Buckingham. In the mystery novel The Murders of Richard III by Elizabeth Peters (1974) the central plot revolves around the debate as to whether Richard III was guilty of these and other crimes. A sympathetic portrayal of Richard III is given in The Founding, the first volume in The Morland Dynasty series by Cynthia Harrod-Eagles.  One film adaptation of Shakespeare's play Richard III is the 1955 version directed and produced by Laurence Olivier, who also played the lead role. Also notable are the 1995 film version starring Ian McKellen, set in a fictional 1930s fascist England, and Looking for Richard, a 1996 documentary film directed by Al Pacino, who plays the title character as well as himself. The play has been adapted for television on several occasions.

Problem: Background: Victor August Herbert (February 1, 1859 - May 26, 1924) was an Irish-born, German-raised American composer, cellist and conductor. Although Herbert enjoyed important careers as a cello soloist and conductor, he is best known for composing many successful operettas that premiered on Broadway from the 1890s to World War I. He was also prominent among the tin pan alley composers and was later a founder of the American Society of Composers, Authors, and Publishers (ASCAP). A prolific composer, Herbert produced two operas, a cantata, 43 operettas, incidental music to 10 plays, 31 compositions for orchestra, nine band compositions, nine cello compositions, five violin compositions with piano or orchestra, 22 piano compositions and numerous songs, choral compositions and orchestrations of works by other composers, among other music.
Context: In 1894 Herbert composed his first operetta, Prince Ananias, for a popular troupe known as The Bostonians. The piece was well received, and Herbert soon composed three more operettas for Broadway, The Wizard of the Nile (1895), The Serenade (1897), which enjoyed international success, and The Fortune Teller (1898), starring Alice Nielsen. Although these achieved popularity, Herbert did not produce any more stage works for several years, focusing on his work with the Pittsburgh Symphony until 1904. Just before leaving that orchestra, he returned to Broadway with his first major hit, Babes in Toyland (1903). Two more successes followed, Mlle. Modiste (1905) and The Red Mill (1906), which solidified Herbert as one of the best-known American composers. He was elected to the National Institute of Arts and Letters in 1908.  Although Herbert's reputation lies with his operettas, he also composed two grand operas. He searched for several years for a libretto that appealed to him, finally finding one by Joseph D. Redding called Natoma that concerned a historical story set in California. He composed the work from 1909 to 1910, and it premiered in Philadelphia on 25 February 1911 with soprano Mary Garden in the title role and the young Irish tenor John McCormack in his opera debut. The opera was well received and was repeated as part of the company's repertory during the next three seasons. It also enjoyed performances in New York City, making its debut there on February 28, 1911. Herbert's other opera, Madeleine, was a much lighter work in one act. On 24 January 1914, it had its premiere at the Metropolitan Opera, but it was not revived beyond that season.  During this period, Herbert continued to compose operettas, producing two of his most successful works, Naughty Marietta (1910) and Sweethearts (1913). Another operetta, Eileen (1917, originally entitled Hearts of Erin), was the fulfillment of Herbert's desire to compose an Irish-themed operetta. The piece treats the Irish Rebellion of 1798 and boasts a rich score. This was the end of Herbert's greatest period of producing full scores for operettas.  By World War I, with the birth of jazz, ragtime and new dance styles like the foxtrot and tango, Herbert reluctantly switched to writing musical comedies. These featured less elaborate ensembles and simpler songs for less classically trained singers than the European-style operettas that had dominated his earlier career. Herbert, during the last years of his career, was frequently asked to compose ballet music for the elaborate production numbers in Broadway revues and the shows of Irving Berlin and Jerome Kern, among others. He was also a contributor to the Ziegfeld Follies every year from 1917 to 1924.
