- Click here for audio of Episode 1098. Today, an old question: who invented the telephone? The University of Houston's College of Engineering presents this series about the machines that make our civilization run, and the people whose ingenuity created them. Ask who really invented the telephone, and you may get the name of a German, Philipp Reis, not Alexander Graham Bell. The common wisdom is that Reis's telephone was only marginal, while Bell's phone really worked. Now Lewis Coe rethinks the priority question in his book, The Telephone and its Several Inventors. Reis was a 26-year-old science teacher when he began work on the telephone in 1860.

Invention of the telephone In the 1880's Meucci was credited with the early invention of inductive loading of telephone wires to increase long-distance signals. Unfortunately, serious burns from an accident, a lack of English, and poor business abilities resulted in Meucci's failing to develop his inventions commercially in America.eucci's 1871 caveat did not mention any of the telephone features later credited to him by his lawyer, and which were published in that Scientific American Supplement, a major reason for the loss of the 'Bell v. Globe and Meucci' patent infringement court case, which was decided against Globe and Meucci.
