Paul Sacher (28 April 1906 – 26 May 1999) was a Swiss conductor, patron and impresario. He founded and conducted the Basler Kammerorchester (1926–1987). He commissioned notable works of composers of the 20th century and premiered them with the chamber orchestra. While better known for his interest in new music, he was also devoted to music of baroque and classical eras; he the founded the Schola Cantorum Basiliensis, institute for early music, in 1933. 　　Sacher studied under Felix Weingartner, among others. In 1926 he founded the chamber orchestra Basler Kammerorchester, which specialized in both modern (twentieth-century) and pre-classical (mid-eighteenth-century) repertory. In 1928 he founded the Basel Chamber Choir. Both the orchestra and choir gave their last performance in 1987. In 1984, the Serenata Basel was formed, with no direct connection to Sacher. They later adopted the name Kammerorchester Basel.
