Telephone
Voice Communication (~1850-1860)
Engineers and scientists were excited that data could be transmitted using electric dot and dash signals through a wire, but encoding and decoding the signal wasn’t easy and required specialized training. They reasoned that there just might be a way to encode and transmit the human voice. Elisha Gray, Antonio Meucci, Alexander Graham Bell and others were working on creating a talking telegraph. Eventually in June 1875, Alexander Graham Bell was the first to be officially awarded a patent on the telephone.
Key Takeaways:
- Human voices could now be transmitted across distances. Human-to-human communication via phone was now fast and personal.
- A much greater amount of information could be communicated in real-time using voice.
- Telephone service progressively expanded from telegraph offices in town all the way into family homes. Voice communication was commonplace.
