Ouvrage consacré au musicien viennois Gustav Mahler (XIXe siècle), qui incarne la transition entre le romantisme finissant et la modernité. Reprend de façon condensée l'ouvrage du même auteur paru en trois volumes en 1983-1984 avec en plus une présentation des oeuvres de Mahler.
The son of an American mother and French father who was a senator and former governor minister, Henry Louis de la Grange studied the humanities in Paris and New York and literature at Aix-en-Provence University and at the Sorbonne. It was in 1945 when attending a performance of Gustav Mahler's Ninth Symphony conducted by Bruno Walter that he first became interested in the composer. He began what became a lifelong investigation of Mahler's life and works, the research of which formed the basis of his multi-volume biography of the composer.
