There's something elfin and even a little mischievous about the 102-year-old man who goes by Walter Arlen. The composer lives in a house near the ocean in Santa Monica, Calif., with his husband of 65 years. But he was born in Austria, in 1920, as Walter Aptowitzer. He grew up in a cosmopolitan cradle of music and high culture: Vienna before the war.
