Mahler never became a teacher, but he gave a lot of encouragement to young composers such as Arnold Schoenberg, Alban Berg, Anton Webern and Alexander Zemlinsky. However, there were music critics in Vienna who were anti-Jewish and made things difficult for him. In 1907 his elder daughter Maria died from scarlet fever. More bad news followed when Mahler was found to have a bad heart. The doctor said he must give up his favourite pastimes: going for walks, cycling and swimming. Mahler had done a tremendous amount for the cultural life of Vienna, but he decided it was time to leave. The last thing he conducted in Vienna was his Second Symphony.
