IN: Giuseppe Fortunino Francesco Verdi (Italian: [dZu'zeppe 'verdi]; 9 or 10 October 1813 - 27 January 1901) was an Italian opera composer. He was born near Busseto to a provincial family of moderate means, and developed a musical education with the help of a local patron. Verdi came to dominate the Italian opera scene after the era of Vincenzo Bellini, Gaetano Donizetti, and Gioachino Rossini, whose works significantly influenced him. By his 30s, he had become one of the pre-eminent opera composers in history.

List of compositions by Giuseppe Verdi  In mid-1834, Verdi sought to acquire Provesi's former post in Busseto but without success. But with Barezzi's help he did obtain the secular post of maestro di musica. He taught, gave lessons, and conducted the Philharmonic for several months before returning to Milan in early 1835. By the following July, he obtained his certification from Lavigna. Eventually in 1835 Verdi became director of the Busseto school with a three-year contract. He married Margherita in May 1836, and by March 1837, she had given birth to their first child, Virginia Maria Luigia on 26 March 1837. Icilio Romano followed on 11 July 1838. Both the children died young, Virginia on 12 August 1838, Ilicio on 22 October 1839.  In 1837, the young composer asked for Massini's assistance to stage his opera in Milan. The La Scala impresario, Bartolomeo Merelli, agreed to put on Oberto (as the reworked opera was now called, with a libretto rewritten by Temistocle Solera) in November 1839. It achieved a respectable 13 additional performances, following which Merelli offered Verdi a contract for three more works.  While Verdi was working on his second opera Un giorno di regno, Margherita died of encephalitis at the age of 26. Verdi adored his wife and children and was devastated by their deaths. Un giorno, a comedy, was premiered only a few months later. It was a flop and only given the one performance. Following its failure, it is claimed Verdi vowed never to compose again, but in his Sketch he recounts how Merelli persuaded him to write a new opera.  Verdi was to claim that he gradually began to work on the music for Nabucco, the libretto of which had originally been rejected by the composer Otto Nicolai: "This verse today, tomorrow that, here a note, there a whole phrase, and little by little the opera was written", he later recalled. By the autumn of 1841 it was complete, originally under the title Nabucodonosor. Well received at its first performance on 9 March 1842, Nabucco underpinned Verdi's success until his retirement from the theatre, twenty-nine operas (including some revised and updated versions) later. At its revival in La Scala for the 1842 autumn season it was given an unprecedented (and later unequalled) total of 57 performances; within three years it had reached (among other venues) Vienna, Lisbon, Barcelona, Berlin, Paris and Hamburg; in 1848 it was heard in New York, in 1850 in Buenos Aires. Porter comments that "similar accounts...could be provided to show how widely and rapidly all [Verdi's] other successful operas were disseminated."

input: Murray Rothbard's parents were David and Rae Rothbard, Jewish immigrants to the U.S. from Poland and Russia, respectively. David Rothbard was a chemist. Murray attended Birch Wathen, a private school in New York City. Rothbard later stated that he much preferred Birch Wathen to the "debasing and egalitarian public school system" he had previously attended in the Bronx.  Rothbard wrote of having grown up as a "right-winger" (adherent of the "Old Right") among friends and neighbors who were "communists or fellow-travelers." Rothbard characterized his immigrant father as an individualist who embraced the American values of minimal government, free enterprise, private property, and "a determination to rise by one's own merits". "[A]ll socialism seemed to me monstrously coercive and abhorrent."  He attended Columbia University, where he received a Bachelor of Arts degree in mathematics in 1945 and, eleven years later, his PhD in economics in 1956. The delay in receiving his PhD was due in part to conflict with his advisor, Joseph Dorfman, and in part to Arthur Burns rejecting his doctoral dissertation. Burns was a longtime friend of the Rothbard family and their neighbor at their Manhattan apartment building. It was only after Burns went on leave from the Columbia faculty to head President Eisenhower's Council of Economic Advisors that Rothbard's thesis was accepted and he received his doctorate. Rothbard later stated that all of his fellow students there were extreme leftists and that he was one of only two Republicans on the Columbia campus at the time.  During the 1940s Rothbard became acquainted with Frank Chodorov and read widely in libertarian-oriented works by Albert Jay Nock, Garet Garrett, Isabel Paterson, H. L. Mencken and others, as well as Austrian economist Ludwig von Mises. In the early 1950s, when Mises was teaching at the Wall Street division of New York University Business School, Rothbard attended Mises' unofficial seminar. Rothbard was greatly influenced by Mises' book, Human Action. Rothbard attracted the attention of the William Volker Fund, a group that provided financial backing to promote various "right-wing" ideologies in the 1950s and early 1960s. The Volker Fund paid Rothbard to write a textbook to explain Human Action in a form which could be used to introduce college undergraduates to Mises' views; a sample chapter he wrote on money and credit won Mises's approval. For ten years, Rothbard was paid a retainer by the Volker Fund, which designated him a "senior analyst." As Rothbard continued his work, he enlarged the project. The result was Rothbard's book Man, Economy, and State, published in 1962. Upon its publication, Mises praised Rothbard's work effusively.
