Schubert met a young soprano named Therese Grob, daughter of a local silk manufacturer, and wrote several of his liturgical works (including a "Salve Regina" and a "Tantum Ergo") for her; she was also a soloist in the premiere of his Mass No. 1 (D. 105) in September 1814. Schubert wanted to marry her, but was hindered by the harsh marriage-consent law of 1815 requiring an aspiring bridegroom to show he had the means to support a family. In November 1816, after failing to gain a musical post in Laibach (now Ljubljana, Slovenia), Schubert sent Grob's brother Heinrich a collection of songs retained by the family into the twentieth century. One of Schubert's most prolific years was 1815. He composed over 20,000 bars of music, more than half of which were for orchestra, including nine church works (despite his being an agnostic), a symphony, and about 140 Lieder. In that year, he was also introduced to Anselm Hüttenbrenner and Franz von Schober, who would become his lifelong friends. Another friend, Johann Mayrhofer, was introduced to him by Spaun in 1815. Throughout 1815, Schubert lived at home with his father. He continued to teach at the school and give private musical instruction, earning enough money for his basic needs, including clothing, manuscript paper, pens, and ink, but with little to no money left over for luxuries. Spaun was well aware that Schubert was discontented with his life at the schoolhouse, and was concerned for Schubert's development intellectually and musically. In May 1816, Spaun moved from his apartment in Landskrongasse (in the inner city) to a new home in the Landstraße suburb; one of the first things he did after he settled into the new home was to invite Schubert to spend a few days with him. This was probably Schubert's first visit away from home or school. Schubert's unhappiness during his years as a schoolteacher possibly showed early signs of depression, and it is virtually certain that Schubert suffered from cyclothymia throughout his life. In 1989 the musicologist Maynard Solomon suggested that Schubert was erotically attracted to men, a thesis that has been heatedly debated. The musicologist and Schubert expert Rita Steblin has said that he was "chasing women". The theory of Schubert's sexuality or "Schubert as Other" has continued to influence current scholarship.
