Hermann Theodor Schrader (1860 – 9 July 1934) was a noted South Australian pianist, violinist and cellist, who had a later academic career in Victoria.
Hermann was born in Adelaide, South Australia the second son of Heinrich Ludwig Christian Schrader (4 February 1832 – 21 February 1880) and his wife Wilhelmine "Menna" Schrader, née Oelmann (c. 1822–1910), who married in 1857. Hermann Schrader sen. arrived in Adelaide from Brunswick, Germany in 1857 and was from 1861 landlord of the Black Horse Hotel in Leigh Street, a singing teacher at the Deutsche Schule run by conducted by Leschen and Niehaus in Wakefield Street, and bandmaster with the Adelaide Regiment, Volunteer Force, then had his own private band. He played the cornet, contrabass tuba and cornopean. He also served on occasion as court interpreter.
Hermann was a student at the Deutsche Schule, Wakefield Street, followed by John Whinham's North Adelaide Grammar School. Around 1878 he left for Germany to study music under Hans von Bülow at the Königliche Musikschule in Munich, returning shortly after his father's early and unexpected death. He made his debut concert appearance in July 1880 at a reunion of the Liedertafel Society at the German Clubhouse in Kapunda, followed in August by one of the "Monday Pops" concerts in the Adelaide Town Hall, when he played one of Mendelssohn's Lieder ohne Worte and Schubert's Scherzo in F Minor, which were very well received. A month later he was the principal soloist at another Town Hall concert with support from Moritz Heuzenroeder, Minna Fischer and others. He and Heuzenroeder frequently shared the stage, usually on violin to Heuzenroeder's piano. In 1883 he was appointed University of Adelaide Examiner in Music with Cecil Sharp and Charles H. Compton, a board which, inter alia, selected Otto Fischer as recipient of an Elder Overseas Scholarship in Music.
