Pearl diving with Walter Benjamin ...

No audio recordings of Walter Benjamin have survived. His voice was once described as beautiful, even melodious—just the sort of voice that would have been suitable for the new medium of radio broadcasting that spread across Germany in the 1920s. If one could pay the fee for a wireless receiver, Benjamin could be heard in the late afternoons or early evenings, often during what was called “Youth Hour.” His topics ranged widely, from a brass works outside Berlin to a fish market in Naples. In one broadcast, he lavished his attention on an antiquarian bookstore with aisles like labyrinths, whose walls were adorned with drawings of enchanted forests and castles. For others, he related “True Dog Stories” or perplexed his young listeners with brain teasers and riddles. He also wrote, and even acted in, a variety of radio plays that satirized the history of German literature or plunged into surrealist fantasy. One such play introduced a lunar creature named Labu who bore the august title “President of the Moon Committee for Earth Research."
