The composer Hans Schaeuble was born in Arosa on 31 May 1906 and died in Zurich on 19 December 1988. His parents were both from Germany. He created 26 operas of all genres and instrumentations, totalling 51 works. All four of these works were premiered before his death on 19 December 1988. He spent the last 20 years of his life revising his oeuvre, sometimes several times, but always marginally. Wealthy from birth, he established the Hans Schaeuble Foundation to support young musicians and musicologists, who primarily take on the works of the founder. The Music for Clarinet and String Orchestra, op.46, from 1961 is the middle of three wind concertos that Schaeuble apparently composed according to plan between 1959 and 1962. The Symphonic-Concertante Music for string orchestra with obbligato piano, op.33, composed in January and February 1949, is Schaeuble's third of a total of five works for piano and orchestra. The Music for 2 Violins and String Orchestra, op.18, is the first of only two violin concertos from Hans Schaeuble's pen. Schaeuble wrote the only 'real' one, the Concerto for Violin and Orchestra, op.24, at the beginning of the war and completed it on 15 December 1940 in Arosa. Composed in Berlin in 1935, the present music, op.18, was published by Bote & Bock in Berlin in 1936, according to Schaeuble. However, no copy of it has survived either in the estate or in the libraries; worse still, the autograph score and the parts were apparently stored by the publisher and were destroyed during the war.
