Who invented the first light bulb record player and movie projector?

The first light bulb was invented by Thomas Edison in 1879, while Emile Berliner is credited with inventing the first practical record player, known as the gramophone, in the late 19th century. The movie projector was developed by several inventors, but Thomas Edison and his assistant, William Kennedy Laurie Dickson, created the Kinetoscope, an early motion picture device, in the 1890s. Each of these inventions played a significant role in advancing their respective fields.
