The volume traces the life and career of Mahler from his birth to his appointment to the Vienna Hofoper. This long awaited revised volume I completes Henry-Louis de La Grange's four-volume English language biography of the Austrian composer Gustav Mahler (1860?1911), which is widely considered to be the definitive work on the subject. The present instalment, covering the years 1860 to 1897, traces the life and career of Mahler from his birth in a small village in Bohemia to his appointment to the Vienna Hofoper, then the most prestigious opera house in the world. It describes his family background, his student days at the Vienna Conservatory, his private life, and his burgeoning career as both conductor and composer. Starting at a small summer theatre in Bad Hall, his first engagements took him to Laibach (Ljubljana), Olm tz (Olomouc), Kassel, Prague, and Leipzig, before he was appointed to principal posts at the important opera houses of Budapest (1888) and Hamburg (1891). By now Mahler had also begun to establish himself as a composer. Some of his major works ? starting with Das Klagende Lied (1881) ? the early Wunderhorn songs, Lieder eines fahrenden Gesellen , and the first three symphonies date from this period of his life. While regularly rejected by contemporary critics, today they are favourites of the concert repertoire. Widely recognised as Gustav Mahler's pre-eminent biographer, Henry-Louis de La Grange (1924?2017) ? author of the 4-volume, 5,000-page definitive study of the composer's life and work ? was awarded a professorship by the government of Austria and an honorary Doctorate from the Juilliard School of Music. He lectured extensively, organised concerts, exhibitions, and music festivals, and contributed to film documentaries and radio features. Together with Maurice Fleuret he founded the M diath que Musicale Mahler in Paris. German musicologist and conductor Sybille Werner started working with Henry-Louis de La Grange in 2003. She has repeatedly lectured and published on the performance history of Mahler's works, and in 2018 received the Mahler Award of the Sociedad Mahler Mexico. Her conducting activities have taken her beyond New York, her former residence, and the USA to Germany, Italy, Japan, Mexico, Poland, and the UK. Currently she is based in Toblach and associated with the Gustav Mahler Music Weeks.
