(b Batavia [now Jakarta], 16 Aug 1863; d Berlin, 12 Aug 1943). Dutch composer. She studied the piano with C.L.W. Wirtz and music theory with Willem Nicolaï in The Hague. She then went to Berlin to study composition with Rudolf Radecke. After a brief return to the Netherlands, where she received counterpoint tuition from Samuel de Lange, she returned to Berlin to study instrumentation with Heinrich Urban. Her first orchestral work, Jolanthe, was performed by the Concertgebouw Orchestra for the opening of the new city theatre in Amsterdam in 1894. Both this and her next work, Nordische fantasie, were frequently performed. In 1896 she conducted the first Dutch performance of a four-movement suite, Königs-Idyllen, inspired by Tennyson's Idylls of the King. In 1898 she wrote and conducted a festive cantata for the opening of the Nationale Tentoonstelling Vrouwenarbeid (National Exhibition of Women's Work) held in The Hague. In 1900 her symphony won second prize from the Allgemeine Deutsche Musikverein and was performed that same year by the Concertgebouw Orchestra conducted by Mengelberg. In 1910 her opera Das Gelöbnis was first performed in the Weimar Hoftheater. She regularly contributed articles to the Dutch music magazines Weekblad voor muziek and Caecilia and ran a column, ‘Letters from Berlin’, in the Algemeen Handelsblad. Through these articles we learn that she greatly admired the music of Wagner and Richard Strauss. Van Oosterzee was knighted by the Order of Oranje-Nassau in 1897 and invited to become a corresponding member of the Maatschappij tot Bevordering der Toonkunst (Association for the Promotion of Music) in 1901. Little is known about the last 25 years of her life. After she died the Algemeen Handelsblad ran an article on her, noting that her music had gradually disappeared from programmes because of the increasing attention to younger composers. All Van Oosterzee's large-scale works are lost, perhaps destroyed in Berlin during World War II. Her opera Das Gelöbnis is an example of Italian verismo in which blood feud, murder and vendetta predominate. Her chamber music is diverse, from simple piano works influenced by her stay in Indonesia (such as the Javanischen Tanz and Malaüshchen Wiegenliedchen from the Sechs leichte Stüke for piano duet), to salon music typical of the 1920s (Zwei Phantasiestücke for piano trio). Her German lieder reflect the influence of Schumann and Brahms, her French songs that of Berlioz.

Town in Silesia, Czech Republic. It is the former Silesian regional capital, with a bilingual Czech-German cultural history. From 1656 to 1660 Pavel Josef Vejvanovský studied at the Jesuit college in Opava. Carl Ditters von Dittersdorf worked in nearby Johannisberg and composed operas for the theatre of the local castle. Beethoven gave concerts in a nearby castle in Hradec nad Moravicí (Ger. Grätz) in 1806 and 1811, as did Liszt in 1841 (Liszt also performed in Opava in 1846 and 1848). Pavel Křížkovský, Janáček's teacher, won a scholarship in Opava in 1832; he studied at the local grammar school from 1834 to 1839. The composer, pianist and organist Eduard Mestenhauser (1832–1912) founded the German Singakademie in 1874; J.F. Hummel (1841–1919) was conductor there and for the German men's choir, 1863–73. Other musicians active in Opava were Bruckner's disciple Ludwig Grande (1865–1940), the violinist Herma Studeny (1886–1973), a disciple of Dvořák and Ševčík, and the composer and conductor Miloš Čeleda (1884–1958).
Opera was given from 1790 in the Theater unter dem Stadtturm (built 1750; rebuilt 1774 after a fire in 1763); in 1794 Mozart’s Die Zauberflöte was staged there. The Městské Divadlo (Municipal Theatre) was built in 1805; major reconstructions were carried out in 1883, in 1909, shortly after World War II and in 1992. Arthur Löwenstein was a conductor there (1929–32); among visiting artists were Marie Gutheil-Schoder and Leo Slezak. Between 1919 and 1938 Czech operas were performed by visiting companies from Ostrava and Olomouc. A professional Czech theatre company (drama, opera, operetta, ballet) was founded in the badly damaged town in 1945. At first, under municipal administration, it was known as the Slezské Národní Divadlo (Silesian National Theatre); after 1949 it became a regional company, making numerous tours. In 1957 it became the Slezské Divadlo Zdeňka Nejedlého; in 1990 it again came under municipal administration and was renamed Slezské Divadlo Opava. The company has performed both Czech and foreign operas from traditional and modern repertories.
Musical associations include the Pěvecko-Hudební Spolek Křížkovský (Křížkovský Singing and Instrumental Club, founded in 1887), Pěvecké Sdružení Slezských Učitelů (Silesian Teachers' Choir, 1906) and Pěvecké Sdružení Slezských Učitelek (Silesian Women Teachers' Choir, 1958). The Silesian Regional Museum houses a musicological centre (founded 1967) which works together with the musicological department of the Institute of Silesian Studies under the aegis of the Czechoslovak Academy of Sciences. The Silesian Musical Archives (founded 1951) contain collections from the Minorite monastery and from the castle in Hradec nad Moravicí. The Věstník matice opavské (Opavian Foundation Gazette) was published from 1891; in 1935 it became the Slezský sborník (Silesian Review). Since 1960 Opava has been the seat of the International Beethoven Society, publishing the journal Československá Beethoveniána. Since 1961 the annual Nationwide Performers' Competition has been held in Hradec.
