Edison Thomas's Phonograph
The phonograph, regarded as the first truly brilliant invention by Thomas Edison and his lifelong favourite, was able to record and replay spoken speech.
Speaking into the receiver would force a needle covered in tin foil to leave indentations on a drum due to the vibration of the voice. Edison eventually used discs and cylinders to permanently record music.
Thomas Edison spoke "Mary had a little lamb" in the first message ever recorded, which shocked and pleased Edison and his employees when they heard it played back to them.
The Light Bulb by Thomas Edison
The light bulb is Thomas Edison's most famous innovation. The lightbulb was not invented by Edison, despite what is commonly believed; it had existed for some time. But at the time, electric lights were costly, inefficient, and unreliable. When Edison joined the contest to create the light bulb, more than twenty different attempts had already been made by other innovators worldwide.
Edison achieved a long-lasting light bulb by inventing a vacuum inside the bulb, selecting the ideal filament, and applying a lower voltage to the bulb. This was a significant advancement that paved the way for other advancements that made the lightbulb more useful and affordable.
The Motion Picture by Thomas Edison
Muybridge's study of motion served as an inspiration for Edison's early motion picture work (1888–1889). The initial Edison invention was a cylinder containing a spiral arrangement of 1/16-inch photos, much like his phonograph. These early motion movies were difficult to focus on and fairly rudimentary when viewed under a microscope. Edison then created the Strip Kinetograph in collaboration with W. K. L. Dickson, utilising George Eastman's enhanced 35 mm celluloid film. The film was positioned behind the shutter and moved by sprockets in a stop-and-go motion. It was cut into continuous strips and perforated along the edges.
