Du Moncel is a scientific publication written in the late 19th century. This work explores the historical and technical developments surrounding the telephone, microphone, and phonograph, detailing the scientific principles that led to these revolutionary inventions. The text discusses various inventors and their contributions to the field of sound transmission, emphasizing the progression of technology in acoustics. The opening of this scientific exploration presents a historical overview of the telephone's origins, tracing back to ancient methods of sound transmission and moving through significant developments leading to the invention of the telephone. It introduces prominent figures in the field, such as Graham Bell and Elisha Gray, and outlines their experimental works leading to the eventual success in transmitting voice electronically.
