Siegfried Borries

In 1957, due to differences with the Berlin Senate on questions of fees, Borries refused to participate in the orchestra's 75th anniversary concert. He was then placed on leave until his final departure from the orchestra on 31 August 1961.

After the end of the war, in 1945, he took over the master classes for violin at the newly founded "International Music Institute Berlin". He also resumed his position as concertmaster of the Philharmonic Orchestra and became director of its chamber music association. From 1948, he taught violin (since 1949 as professor) at the Berlin University of the Arts and developed in the following years a lively concert activity as soloist and chamber musician in Germany and abroad.

After his secondary school leaving certificate and corresponding preliminary studies, Borries studied at the Rheinische Musikschule [de] in the master class of professor Bram Eldering from 1929. At the first International Competition for Voice and Violin in Vienna in 1932, he was the only German among 300 applicants to receive the "Großen Internationalen Preis" and a few months later, in October 1932, also the "Mendelssohn Prize Berlin" from the State Academy of Music in Berlin. At the age of 20, on 1 January 1933, he was appointed 1st concertmaster of the Berlin Philharmonic by Wilhelm Furtwängler. In May 1936, he was awarded the first ever "Musikpreis der Reichshauptstadt Berlin". Also in 1936, he became a teacher at the Stern Conservatory. At the Reich Music Days in the summer of 1939, Borries was awarded the National Music Prize 1939 as the best German violinist of the next generation of soloists. From 1941 to 1945, Borries was special concert master of the Staatskapelle Berlin under Herbert von Karajan's authority.

As a chamber musician, he played from 1933 to 1945 together with his Philharmonic colleagues Heinrich Breiden, flute and Hans Ahlgrimm, 2nd violin in the Borries-Breiden-Ahlgrimm Trio. Borries was listed as an important violinist of the NS State on Goebbels' Gottbegnadeten list.
