Bohemian Provisional Theater Orchestra. Dvořák played viola in the orchestra beginning in 1862. Dvořák could hardly afford concert tickets, and playing in the orchestra gave him a chance to hear music, mainly operas. In July 1863, Dvořák played in a program devoted to the German composer Richard Wagner, who conducted the orchestra. Dvořák had had "unbounded admiration" for Wagner since 1857. In 1862, Dvořák had begun composing his first string quartet. In 1864, Dvořák agreed to share the rent of a flat located in Prague's Žižkov district with five other people, who also included violinist Mořic Anger and Karel Čech, who later became a singer. In 1866, Maýr was replaced as chief conductor by Bedřich Smetana. Dvořák was making about $7.50 a month. The constant need to supplement his income pushed him to give piano lessons. It was through these piano lessons that he met his future wife. He originally fell in love with his pupil and colleague from the Provisional Theater, Josefína Čermáková, for whom he apparently composed the song-cycle "Cypress Trees". However, she never returned his love and ended up marrying another man. In 1873 Dvořák married Josefina's younger sister, Anna Čermáková (1854–1931). They had nine children – Otakar (1874–1877), Josefa (1875–1875), Růžena (1876–1877), Otýlie (1878–1905), Anna (1880–1923), Magdalena (1881–1952), Antonín (1883–1956), Otakar (1885–1961) and Aloisie (1888–1967). In 1898 his daughter Otýlie married his student, the composer Josef Suk. His son Otakar wrote a book about him. Composer and organist Dvořák called his String Quintet in A minor (1861) his Opus 1, and his First String Quartet (1862) his Opus 2, although the chronological Burghauser Catalogue numbers these as B.6 and B.7, showing five earlier compositions without opus numbers. In the early 1860s, Dvořák also made his first symphonic attempts, some of which he self-critically burned. The manuscript of a symphony in C minor without opus number, B.9, composed in 1865, was preserved. This symphony has come to be numbered as Dvořák's First (see under "Works"). His first composing attempts passed without critical reception or public performances. His compositions up through 1870, according to the Burghauser Catalogue either had no known premieres, or were premiered in 1888 or later. For example, the Third String Quartet, B.18, was written in about 1869 but first published posthumously in 1964 and premiered in 1969. In 1870, he composed his first opera, Alfred, over the course of five months from May to
