Question: Henry Purcell and Paul Hindemith, have which occupation in common?
Context: John Blow (baptised 23 February 1649 – 1 October 1708) was an English Baroque composer and organist, appointed to Westminster Abbey in 1669.  His pupils included William Croft, Jeremiah Clarke and Henry Purcell.  In 1685 he was named a private musician to James II.  His only stage composition, "Venus and Adonis" (ca. 1680–1687), was thought to influence Henry Purcell's later opera "Dido and Aeneas".  In 1687 he became choirmaster at St Paul's Cathedral, where many of his pieces were performed.  In 1699 he was appointed to the newly created post of Composer to the Chapel Royal. Paul Hindemith ( ) (16 November 1895 – 28 December 1963) was a prolific German composer, violist, violinist, teacher and conductor.  Notable compositions include his song cycle "Das Marienleben" (1923), "Der Schwanendreher" for viola and orchestra (1935), and opera "Mathis der Maler" (1938).  Hindemith's most popular work, both on record and in the concert hall, is likely the "Symphonic Metamorphosis of Themes by Carl Maria von Weber", written in 1943. The Purcell Society, founded in 1876 (principally by William Hayman Cummings) is an organization dedicated to making the complete musical works of Henry Purcell available.  Between 1876 and 1965, scores of all the known works of Purcell were published, in 32 volumes.  Advances in musical scholarship and editorial techniques in the decades after the first volumes were issued meant that by the second half of the 20th century they were no longer meeting the needs of users.  Beginning in the 1960s, the Purcell Society began to issue revised versions of the scores.  The website gives details of the scores in the revised series that are currently available. Franklin Bershir Zimmerman (born June 20, 1923) is an American musicologist and conductor who has published extensively in the field of Baroque music, and particularly on the English composer, Henry Purcell.  He is most known for his complete catalogue of Purcell's works, considered "one of the most crucial contributions to Purcell research".  Each work in the catalogue is given a "Z number" which derives from Zimmerman's surname. Edward Henry Purcell (died 1765), organist, printer, and music publisher, was the son of Edward Purcell, and grandson of the English Baroque master, Henry Purcell.  He was a chorister in the Chapel Royal in 1737.  Upon the death of his father in 1740, he succeeded him as organist of St Clement, Eastcheap. The Purcell–Killingsworth House, now the Garden Path Inn bed & breakfast, is a historic residence in Columbia, Alabama.  Also known as Traveler's Rest, it was completed in 1890 by William Henry Purcell (1845-1910), a prominent Columbia businessman and politician.  Purcell's business interests included a steamboat landing on the Chattahoochee River.  The bed and breakfast has three guestrooms. The international Paul Hindemith Prize promotes outstanding contemporary composers within the framework of the Schleswig-Holstein Music Festival (SHMF).  The award commemorates the musical pedagogy of Paul Hindemith, who wrote the composition "Plöner Musiktag" in 1932 on behalf of the Staatliche Bildungsanstalt Plön.  The music prize is endowed with 20,000 € and goes together with a composition commission.  The prize is presented annually by the Hindemith Foundation in Blonay (Switzerland), the Walter and Käthe Busche Foundation, the Rudolf and Erika Koch Foundation, the Gerhard Trede Foundation, the Franz Wirth Memorial Trust and the Cultural Office of the Free and Hanseatic City of Hamburg since 1990.  Since 2010, the winner is found partly by a composition competition.  The work of the prize winner is to be premiered within the framework of the Schleswig-Holstein Music Festival. Dido and Aeneas (Z. 626) is an opera in a prologue and three acts, written by the English Baroque composer Henry Purcell with a libretto by Nahum Tate.  The dates of the composition and first performance of the opera are uncertain.  It was composed no later than July 1688, and had been performed at Josias Priest's girls' school in London by the end of 1689.  Some scholars argue for a date of composition as early as 1683.  The story is based on Book IV of Virgil's "Aeneid".  It recounts the love of Dido, Queen of Carthage, for the Trojan hero Aeneas, and her despair when he abandons her.  A monumental work in Baroque opera, "Dido and Aeneas" is remembered as one of Purcell's foremost theatrical works.  It was also Purcell's only true opera, as well as his only all-sung dramatic work.  One of the earliest known English operas, it owes much to John Blow's "Venus and Adonis", both in structure and in overall effect.  The influence of Cavalli's opera "Didone" is also apparent. The Fairy-Queen (1692; Purcell catalogue number Z.629) is a masque or semi-opera by Henry Purcell; a "Restoration spectacular".  The libretto is an anonymous adaptation of William Shakespeare's wedding comedy "A Midsummer Night's Dream".  First performed in 1692, "The Fairy-Queen" was composed three years before Purcell's death at the age of 35.  Following his death, the score was lost and only rediscovered early in the twentieth century. Henry Purcell ( or ; c. 10 September 1659 – 21 November 1695) was an English composer.  Although incorporating Italian and French stylistic elements into his compositions, Purcell's legacy was a uniquely English form of Baroque music.  He is generally considered to be one of the greatest English composers; no other native-born English composer approached his fame until Edward Elgar, Ralph Vaughan Williams, William Walton and Benjamin Britten in the 20th century.
