Telegraphy

What is Telegraphy and How Did It Shape Communication?

Telegraphy, the long-distance transmission of messages using symbolic codes rather than physical exchanges, has a rich history that spans centuries. From ancient China to the modern era, telegraphic communication has transformed how we share information.

The Early Beginnings: Optical Telegraphs and Beyond

Have you ever wondered about the earliest forms of long-distance communication? The optical telegraph, which used towers with shutters or paddles signaling to each other, was one such system. In 1792, Claude Chappe established a line between Paris and Lille, carrying dispatches for war efforts. This system was swift but dependent on weather and daylight.

The Arrival of Electric Telegraphy

But what truly revolutionized communication was the electric telegraph. In 1837, Cooke and Wheatstone demonstrated their five-needle system on the London and Birmingham Railway. The Morse system, developed in the United States by Samuel Morse, became widely adopted as the standard for continental European telegraphy in 1851.

From Telegraph to Telex: A Journey Through Time

The telex, a public network of teleprinters that used rotary dialing and Baudot code, emerged after electric telegraphy became available. It was initially developed in Germany in 1926 and introduced to Canada and the US in the late 1950s. Telex speed was approximately 66 words per minute, later replaced by ASCII, a seven-bit code that supported more characters.

The Decline of Telegraphy: A Tale of Technological Evolution

As technology advanced, so did communication methods. The telephone, invented by Alexander Graham Bell in 1876, began to compete with the telegraph. By 1920, telephone use had grown significantly, leading Western Union to give up its patent battle with Bell. Despite some brief resurgences during World War I and after the Second World War, new technology improved communication, causing a decline in telegram usage.

Impact on Society: The Telegraph’s Role in Shaping Industries

The telegraph had an enormous effect on three industries: finance, newspapers, and railways. It facilitated the growth of organizations in these sectors, reduced information costs, and drove down transaction costs. Worldwide telegraphy changed news reporting, with journalists using it for war reporting as early as 1846.

Women in Telegraphy: A High-Paying Job

Interestingly, the jobs of telegraph operators, particularly in the UK and US, were highly attractive to women due to their high pay compared to other available work. This was a significant shift in employment opportunities for women during that era.

The Economic Impact: A Parallel with the Internet?

Economists recognized the importance of the telegraph alongside the invention of printing. Its economic impact wasn’t studied until parallels were drawn with the rise of the internet, highlighting its significance in transforming global communication.

Conclusion: The Legacy of Telegraphy

The legacy of telegraphy is profound. It not only transformed communication but also shaped industries and societies in ways that anticipated many characteristics of the modern internet age. As we look back, it’s clear that the telegraph was more than just a tool for sending messages; it was a catalyst for change.
