    Early audio recorder/player ?
  • Ross said:
    Funny that 1923–1929 is well before the invention of the Leslie speaker, which this definitely resembles.
  • Ross said:
    The nameplate on the speaker horn says Western Electric and maybe model 518-W? If so, that was a domestic radio speaker and probably wouldn't deliver siren-level volume. The question remains what it is doing on the spinning rig—it looks like there are slip rings to make the electrical connection while spinning. Radio special effects?

    "Louis Jean Lumière (1864 - 1948), and his brother Auguste Lumière were among the earliest filmmakers. (Appropriately, "lumière" translates as "light" in English.) "Their father, Charles Antoine Lumière (1840-1911), ran a photographic firm and both brothers worked for him: Louis as a physicist and Auguste as a manager. Louis had made some improvements to the still-photograph process, the most notable being the dry-plate process, which was a major step towards moving images." -- Wikipedia

    How odd! His name is Odd Dahl, and he went adventuring with a Roald. I guess Roald and Dahl are common Norwegian names.

    Seems an unusual name 'Odd' though I guess that isn't the case in Norway. Really clear photograph, looks like it could have been taken yesterday. His wife is very lovely and is stylishly dressed even on expedition.
