Aloys Georg Fleischmann (born 24 April 1880 in Dachau; died 3 January 1964 in Cork) was a German composer, cathedral organist and choirmaster.
He was the only child of the Dachau shoemaker and founding member of the Dachau choir, the Liedertafel, Alois Fleischmann (1844–1914) and of Magdalena née Deger (1846–1928). From 1887–1894 he attended the Dachau primary school for boys. He was given private classes in music, music theory and Latin and in 1896 he was admitted to the preparatory two-year course at the Royal Academy of Music in Munich, today the Hochschule für Musik und Theater München. Having passed the entrance examination, he studied there from 1898–1901 taking the subjects organ, conducting and, with Josef Rheinberger, composition. He graduated with first class honours in all subjects.
In January 1902 he was appointed organist and choirmaster to the parish church of St. Jakob in Dachau. There he founded a choir school and a school of music, in which children could learn music and purchase instruments at minimal cost. With the support of musician friends in Munich and members of the artists’ colony of Dachau (Hans von Hayek, Adolf Hölzel, August Pfaltz, Hermann Stockmann) he worked to revive the local tradition of Christmas children’s festivals, composing the music for a nativity play every year from 1903–1906. In 1905 he produced his Die Nacht der Wunder [The Night of Wonders] based on a text by Selma Lagerlöf, with stage design and costumes by von Hayek, Pfaltz and Stockmann. The Dachau orchestral musicians (including Adolf Hölzel) were augmented by members of the Munich court orchestra and choir. The play was highly successful, was widely reviewed, even in New York.
In 1905 Fleischmann married the Irish pianist Tilly Swertz, who had just graduated from the Royal Academy of Music in Munich. Her parents had emigrated from Dachau to Cork in 1879, where her father, Hans Conrad Swertz, became organist and choirmaster at the Catholic Cathedral of St Mary and St Anne. In 1906, Fleischmann was appointed to his father-in-law’s post in Cork; he worked there until 1961, when his health failed.
