A volunteer at Gaslight Gathering's "Hall of Wonders" talks to visitors about the Edison phonograph, playing antiques from her family's collection.
Here the volunteer removes a pair of early headphones from a small phonograph and prepares to connect the small speaker horn. All while con goers in their steampunk finery eagerly wait.
In the foreground you can see the large trumpet/speaker horn of a larger phonograph.
My dad found me this turn of the century Edison phonograph. It plays beautifully and came with about 30 records. As is usually the story, it was in somebody's barn. The neat thing about it is that it still had the original bill of sale.

Thomas Alva Edison (1847 - 1931): In 1878, Edison began work on an electric lamp and sought a material that could be electrically heated to incandescence in a vacuum. At first he used platinum wire in glass bulbs at 10 volts. He connected these bulbs in series to utilize a higher supply voltage; however, he realized that independent lamp control would be necessary for home and office use. He then developed a three-wire system with a supply of 220 volts DC. Each lamp operated at 110 volts, and the higher voltage required a resistance vastly greater than that of platinum. Edison conducted an extensive search for a filament material to replace platinum until, on Oct. 21, 1879, he demonstrated a lamp containing a carbonized cotton thread that glowed for 40 hours.
1882 Edison installed the first large central power station on Pearl Street in New York City in 1882; its steam-driven generators of 900 horsepower provided enough power for 7,200 lamps. He consistently fought the use of alternating current AC, and continued to market direct current DC systems. This eventually destroyed this arm of his marketing empire due to inadequate technology. During his experiments on the incandescent bulb, Edison noted a flow of electricity from a hot filament across a vacuum to a metal wire. This effect, known as thermionic emission, or the Edison effect, was the foundation of the work later refined by Lee De Forest to create the Audion.
Detroit Edison #001 was the second DE SD40 I'd seen that January, 1992 day. Ahead OF IT IS U30C #018. I was not expecting to see DE locomotives, let alone U30Cs, along the Conrail line in Brownsville, PA.

Three-Quarters Rear View of the Generator
Many of the small parts are missing from the dynamo. Much of the distribution switch is gone, as are the lifting eyebolt and the ballast bulb that would have been screwed into a socket on top of the field coil crossbar. Still, the main iron castings and the coils remain, a legacy for the students of the Massachusetts Institute of Technology.
The dynamo is about five feet tall and seven feet long, overall. And yes, it's painted bright screaming yellow, although Edison's plant originally painted them black.
Engineers and technicians at Edison originally nicknamed this series, "Long-Legged Mary-Ann," but that was quickly Bowdlerized to "Long-Waisted Mary-Ann."

The Thomas Edison Center at Menlo Park NJ, also known as the Menlo Park Museum / Edison Memorial Tower, is a memorial to inventor and businessman Thomas Alva Edison, located in the Menlo Park area of Edison, New Jersey. The tower and museum were dedicated on February 11, 1938, on what would have been the inventor's 91st birthday.
The tower marks the location of Edison's Menlo Park laboratory. Edison and his staff later relocated to West Orange, NJ in 1884 to what is now the Thomas Edison National Historical Park, after which the original buildings began to deteriorate. By 1926 most of the buildings had either collapsed or burned, and the only two remaining buildings were moved to Greenfield Village in Dearborn, Michigan.
The Tower, which rises 131 feet above the Terrace, is topped by a 25 foot high Bulb made of Pyrex segments.
However, the Tower has deteriorated to the point where the concrete is crumbling, exposing the corroded reinforcing rods in its walls. It has been closed to the public for years and a chain link fence keeps would-be visitors at a distance to protect them from falling masonry. Preservation New Jersey has named it one of the state's top endangered sites.
The tower is currently in early stages of restoration with plans to open it again one day.
