“the unconventional picture was recorded with a pinhole camera made from a drink can lined with a piece of photographic paper. Fixed to a single spot for the entire exposure, the simple camera continuously records the Sun’s path each day as a glowing trail burned into the photosensitive paper. … Dark gaps in the daily arcs are caused by cloud cover”

Image description: National Museum of American History curator Carlene Stephens examines a glass disc recording that was made in Alexander Graham Bell’s Volta Lab. The disc contains the audio of a male voice repeating “Mary had a little lamb” twice.
In December, scholars recovered sound from this and other recordings made over 100 years ago. Until now, the technology to listen to the recordings without damaging the objects was not available. Learn more about how they recovered the audio.
