THE HISTORY OF ADT

The #1 security provider in America has a remarkable history, which

began with a stock ticker. Check out all the changes ADT has gone

through over the years.

1867GOLD AND STOCK TELEGRAPH COMPANY

Edward Calahan invents the stock ticker and forms the Gold and Stock Telegraph Company. This opens the door for New York brokerage firms to get up-to-the-minute information from the stock exchange floor. The Gold and Stock Telegraph Company also develops a messenger system that sends instructions to and from the stock exchange floor.

1870THE BREAK-IN AND NEW SECURITY SYSTEM

The president of the Gold and Stock Telegraph Company, Elisha Andrews, wakes up and finds a burglar in his home. Calahan creates a telegraph-based alert system for Andrews' home and eventually connects 50 of Andrews' neighbors to a central station where all the alert boxes are monitored. This system quickly expands throughout New York City.

Calahan helps create the American District Telegraph (ADT) Company, which consolidates over 50 local alert

system companies in the New York area.

1874AMERICAN DISTRICT TELEGRAPH IS FORMED

Police and Fire AlertsADT expands its messenger and

alarm services to include standardized police and fire alerts, in

addition to messenger services for calling doctors and carriages.

1870s - 1880s

ADT develops a service that sends messenger watchmen, also known as "roundsmen," around neighborhoods. The roundsmen's job is to check in at signal boxes at designated times, which indicates to ADT headquarters that neighborhoods are secure.

Clowry sees the long-term benefit of security services and the eventual decline of messenger services, so he separates the two within the company and makes ADT the security services branch of the business.
