ADT history

In 1863, Edward A. Calahan invented a stock ticker and formed the Gold and Stock Telegraph Company in 1867 to exploit the technology. Gold and Stock also developed a messenger system that sent instructions to and from the stock exchange floor. Three years later, the president of Gold and Stock Telegraph Company woke up to a burglar in his home, which inspired him to create a telegraph-based alert system.
