One characteristic incident of his fearlessness occurred when friends of Mahler recommended the Berlin Royal Opera to engage him just before he had signed to go to Hamburg. The intendant at the German capital, who was said to be anti-Semitic, is reported to have replied, ‘We cannot engage Mahler here, as we do not like the shape of his nose.’ When in 1897 Vienna offered Mahler the directorial and managerial control of its opera, Berlin suddenly awoke to the importance of the artist who was leaving Germany, and made him a proposition financially better than the one from Vienna. Mahler at once signed the contract to go to the banks of the Danube and telegraphed Berlin: ‘Regret that I cannot accept. My nose still the same shape.’
