The APO Orchestra was constituted as such in 1922, and prospered with its colloaboration with the local Wagner Association, reaching its zenith under the baton of Swiss conductor Ernest Ansermet. The great depression later limited its activity sharply, and the orchestra was nearly closed in 1935, highlighting the need for state support. Accordingly, the Buenos Aires Symphony (today the Buenos Aires Philharmonic) was founded in 1947, and in 1948, the State Symphony Orchestra.
