Philipp Reis (1834-1874) was a German inventor and physicist best known for his pioneering work on the development of the early telephone. Despite not having a formal background in electrical engineering, he had a keen interest in the emerging field of telecommunication and electrical communication.
In 1861, Reis constructed an early prototype of a device that he called the “telephon” (later known as the Reis telephone). His invention utilized a diaphragm that vibrated in response to sound waves, and these vibrations were transformed into electrical signals. The signals were then transmitted through a wire to a receiver where they were converted back into sound waves, allowing for voice transmission over distances. While Reis’s invention represented a significant step forward in the field of telecommunication, it suffered from transmission issues over longer distances. Despite these shortcomings, Reis’s work laid the foundation for further advancements in telephony.
Sadly, Philipp Reis did not live to witness the full impact of his invention. He struggled with health problems and financial difficulties, and he passed away at the age of 40 on January 14, 1874.
This new edition is dedicated to Dr. Larry Millstein, accomplished leader in the study of scientific inventions and innovations.
