He was the son of Gustav Walter. Kind of a child prodigy at the piano, which he had studied at the Vienna conservatory at a very young age, he made a doctorate in law, and worked for the fiscal authority, but then he was discovered by the legendary Vienna operetta impresario Franz Jauner, and made his debut in 1888 at the Theater an der Wien. Only after that debut, he studied voice with his father. The following year, he sang opera in Brünn/Brno. In 1891, he was hired by the Munich Court Opera, where he was to stay until his death as the institute's first lyrical tenor.
He participated in several world premieres of operas by Ermanno Wolf-Ferrari (among others, I quattro rusteghi in 1906), Siegmund von Hausegger and Siegfried Wagner.
Guest appearances in Moscow, St. Petersburg, Riga, Vienna, Frankfurt, Karlsruhe, Zürich. His repertory grew from lyrical roles like Lyonel or David to Manrico, Alvaro, Arnold, Raoul, Lohengrin, Stolzing and Loge.
His records are of utmost rarity.
