The Victorian Internet

Next month marks the 150th anniversary of the first attempt to lay an Atlantic telegraph cable. In July 1857, the job of laying 2,500 tons of cable across the ocean began. Though the attempt failed (and it would take another nine years for a properly working telegraphy link between Britain and America to function), the anniversary marks an important milestone in the coming of, what Marshall McLuhan was to call over a hundred years later, “the global village”.

The transatlantic cable is one of the important milestones of telegraphy covered in English author Tom Standage’s 1998 book “The Victorian Internet”. Standage’s thesis in the book is that the way in which the telegraph revolutionised the 19th century world is remarkably similar to how the Internet is doing the same thing 150 years later. Both communication mechanisms have proved immune to regulation while both also annihilated distance, revolutionised business, and gave rise to new forms of vocabulary, crime and romance.

Standage traces the beginning of telegraphy back to a bizarre experiment that zapped Parisian monks in 1746. The French scientist Abbe Jean-Antoine Nollet was dishing out electric shocks to a line of 200 unsuspecting Carthusian monks each carrying 7.5 metres of iron wire. Nollet’s electrotherapy proved that electricity could travel quickly over great distance and held out the promise of high speed signalling between remote places.

But the first practical signalling device didn’t involve electric wires. Fifty years after Nollet, his compatriot Claude Chappe evolved a messaging system out of coded black-and-white panels, synchronised clocks and a telescope. In 1791 he sent a message to his brother 16kms away which read in French “if you succeed, you will be covered in glory”. Chappe called his new invention “le télégraphe” from the Greek words for 'far writer'. Chappe expanded his design to do away with the clocks and used a regulating rotating arm which allowed for 94 code symbols. The new post-revolutionary government quickly saw the potential of the new invention and began to build a network of towers to ferry news between towns.

Napoleon was a firm believer in the telegraph and in 1804 he ordered the construction of a line from Paris to Milan. Not to be outdone, Britain followed suit and by the 1830s telegraph towers were springing up all over Europe. But the optical telegraph was fundamentally flawed. Towers were expensive to build and the process needed clear daylight to work. What was needed was an electric telegraph and the race was on to build the prototype.

In 1820, Danish physicist Hans Oersted discovered that an electric current produces a magnetic field which will deflect a compass needle. That same year the German Johann Schweigger (who also named the element chlorine) invented the galvanometer. In conjunction with the electromagnet and the voltaic battery, the galvanometer was the foundation of a working electric telegraph. Two amateur scientists separated by the Atlantic Ocean and unknown to each other were to make it work: Samuel Morse in New Haven and William Fothergill Cooke in London. Both men patented their work in 1837.

Cooke’s English telegraph was greatly helped by Professor Charles Wheatstone who knew how to get signals to travel long distances. The two formed an uneasy partnership. Wheatstone was first and foremost an experimental scientist while Cooke was a go-getting entrepreneur. But together they successfully designed and patented a five-needle telegraph that could allow for 20 letters (C, J, Q, U, X and Z were the unlucky letters who missed out).

While Cooke and Wheatstone took a few months to perfect the telegraph, Morse spent five years getting his invention up and running. His design was overly complex and he ran into similar issues in getting signals to travel long distances. He was greatly assisted by Alfred Vail who became a partner in his venture. They developed the code that bears Morse’s name based on using long and short bursts of current. They also simplified the design to make a working telegraph. All they had to do now was sell it.

But he had difficulty convincing sceptics they had a useful new device. Morse failed to win over US congress and was equally unsuccessful on a sales trip to Europe. Cooke did marginally better and managed to get the Great Western Railway to run a 21km telegraph link between Paddington and West Drayton stations. But even then, the railway lost interest and Cooke had to front up his own money to extend the line to Slough. By 1841 Cooke thought his new invention was foundering.

Back in the US, Morse eventually won some government funding to build an experimental line. He ran a line alongside the 64km railway track between Washington and Baltimore. Before it was completely finished, Morse used the line to transmit the Whig Party presidential nomination in Baltimore and did so 64 minutes in advance of the news arriving in Washington by train. Three weeks later, on 24 May 1844, Morse officially inaugurated the line from Washington to Vail in Baltimore sending a quote from the Book of Numbers 23:23 “What hath God wrought.”

In Britain, the telegraph took off a year later when it was used to transmit news from Windsor Castle to London. Queen Victoria gave birth to her second son Alfred Ernest on 6 August 1844 and within 40 minutes, “The Times” was announcing the news on the streets of London saying it was “indebted to the extraordinary power of the Electro-Magnetic Telegraph”. Having proved its prowess to the press, it was soon impressing the police too. The telegraph was used to apprehend a killer. John Tawell murdered his mistress and he absconded by train from the scene of the crime in Slough. Police sent his description on by telegraph ‘dressed like a Kwaker’ (in the absence of Q’s) and he was easily apprehended at the other end. The telegraph wires were subsequently lauded as “the cords that hung John Tawell”.

Across the Atlantic, the US congress remained apathetic to Morse’s version despite the success of his Washington experiments. He teamed up with Amos Kendall who proposed to set up lines privately. The men set up the Magnetic Telegraph Company and built lines towards Philadelphia, Boston, Buffalo and New York. Kendall advertised in the New York newspapers saying the fee for sending a telegraph was 25 cents for 10 words. The business quickly began making profits.

Once established, telegraph growth was explosive. By 1850, there was almost 20,000kms of wire in the US alone. It was used by bankers, merchants, government, police, business, shipping, courts and what one British writer called “messages of every character usually sent by the mail”. The Great Exhibition of 1851 in London had 13 different designs for improvements on the telegraph. By 1852, Prussia had laid 2,400 kms of lines radiating out from Berlin. Austria and Canada nearly had as much and lines were being laid in Italy, Spain, Russia, Holland, Australia, Chile and Cuba. Only France remained obstinate, reluctant to abandon the optical telegraphy they had given to the world 50 years earlier.

Messages were quickly dubbed ‘telegrams’ and sent by central telegraph offices to their destination office before being transcribed onto paper. Telegraph messenger boys would then take the messages to the recipient. Messenger boy was an occupation seen to be a good stepping stone to success; both Thomas Edison and Andrew Carnegie both started their careers in this way.

As more countries became connected, they soon wanted to talk to each other. Prussia and Austria signed the first interconnection treaty in 1849 and soon spread to the rest of mainland Europe. But until someone could solve the problem of underwater cables due to the deterioration of rubber in water, Britain would remain isolated. The solution was south-east Asian gutta-percha, a kind of rubbery gum that is hard at room temperature but malleable and soft in hot water. The first direct message was sent from London to Paris in 1852. Ireland was linked a year later. But deepwater cable-laying across the Atlantic remained a distant dream.

The independently wealthy Cyrus Field entertained that dream for most of the 1850s. As stated earlier, the first cable was laid in 1857 but snapped as did a replacement cable. A third cable did successfully cross the Atlantic a year later but was very slow and lasted just three weeks before extinguishing forever. Aided by the Scottish scientist William Thomson (later Lord Kelvin) an enquiry into the failed cable demonstrated the conducting core was too small and the use of high voltage induction coils destroyed the cables insulation. In July 1866 the two continents were linked by a newer sturdy cable which was quickly duplicated. Cyrus Field was hailed as “the Columbus of our time”.

By the 1850s congestion was a major problem for telegraph offices. Bottlenecks were arising as messages were held up due to the enormous traffic. London solved the problem by using steam-powered pneumatic tubes to carry messages short distances. The idea was copied in other English cities and spread worldwide. In Paris the system was extensive enough to often avoid sending telegraphs at all. In New York the tubes were large enough to carry large parcels and on one occasion a cat was sent from one post office to another by pneumatic tube.

By the 1870s, the Victorian Internet was in place. Cables reached India, China and Japan in 1870, Australia a year later and South America in 1874. The world had over a million kms of wire and 48,000 kms of submarine cable linking 20,000 towns and villages. Messages could go from London to Bombay and back in under 4 minutes. The newspaper named after the invention itself, the Daily Telegraph, proclaimed that “time itself was telegraphed out of existence”.

But newspapers weren’t always so positive about the virtues of the telegraph. In the early days, the press saw it as an ominous development that might put them out of business. But while telegraphs could quickly transport news, it could not easily distribute news to readers. So the newspapers formed networks of reporters who dispatched their news from distant places. These networks became known as news agencies. The New York Associated Press began in 1848 and soon dominated the selling of news to newspapers. In Europe Paul Julius Reuter established his own agency, initially by carrier pigeon and eventually by telegraph.

The Times reporter William Howard Russell was the world’s first war correspondent when he sent his dispatches back to London from the front line of the Crimean war. Russell was not allowed to use the Black Sea cable specifically built by Britain for the war but his otherwise speedy missives highlighted military inefficiencies and made a national hero out of Florence Nightingale.

But by the 1870s the dominant era of the telegraph was about to end. Most offices now had automatic telegraphs capable of up to 400 words a minute - ten times faster than the quickest human operators. First duplex and then quadruplex systems were developed to carry four streams of traffic simultaneously. The technology changed telegraphy into a low-skill occupation. But it was the invention of the ‘harmonic telegraph’ that was to have the greatest effect.

Harmonic telegraphs distinguish notes of different pitch by using reeds vibrating at different frequencies. Elisha Gray and Alexander Graham Bell were both working on variations of harmonic machines which they realised were capable of making more than mere telegraphy. In 1876 Bell filed a patent for a machine to transmit the human voice when he found out that Gray was working on the same goal. By the end of the year, the ‘telephone’ was ready for the world. Initially seen as a speaking telegraph, it became an instant success going from 230 handsets in 1877 to 30,000 three years later.

Samuel Morse died in 1872, aged 81. Edison’s invention of the incandescent light bulb in 1879 was the final straw for the telegraph. Thanks to Edison, Tesla and others, it was now the electric age and the telegraphic journals began to rename themselves. The Telegraphers’ Advocate became the Electric Age, the Operator became Electrical World, and The Telegraphic Journal became the Electrical Review. By the end of the century, the telephone reigned supreme. The telegraph’s golden age was over.

Cyrus Field and the Transatlantic Cable

In 1812, British soldiers


Cyrus West Field is a giant figure in the history of international communications. In 1844 Samuel Morse said a telegraph line would be established across the Atlantic linking Britain and the US in real time. It was to be over 20 years before Cyrus Field could prove him right.

Ten years before Morse's prediction, the 15-year-old Field was starting his working life as an office boy in New York’s first department store, A. T. Stewart. Co. Cyrus did well enough that his salary was doubled each year until he left to join a paper manufacturing company. By 1839, aged 20, he was a partner in the paper wholesaler E. Root and Company. He proved an extremely savvy paper merchant. Profits from business ventures allowed him to retire at 33 with a quarter of a million dollars. His wealth allowed him to concentrate on a sudden burning passion: laying the first telegraphic cable across the Atlantic Ocean.

In 1854, he was approached by Frederick Gisborne, the developer of the cross-Newfoundland telegraph line. Gisborne’s company was in financial strife and he tried to persuade Field to invest in the company. Field was not keen but the meeting did produce an epiphany. As his brother Henry Field reported after Gisborne left the meeting, "Mr Field took the globe which was standing in the library and began to turn it over. It was while thus studying the globe that the idea first occurred to him, that the telegraph might be carried further still, and be made to span the Atlantic Ocean."

The globe showed Field that it might be possible to link Europe and North America via the two nearest land points: Newfoundland and the west of Ireland. It would shorten the time for messages to cross the ocean by two weeks.

Any cable living on the bottom of the ocean would need good waterproofing and electrical insulation. Samuel Canning had recently identified Gutta-percha, a resin from the Isonandra Gutta tree in Malaya as a suitable insulating material.

Field also knew that the transatlantic project would require an enormous amount of capital. From his home in Gramercy Park, he galvanised his wealthy neighbours and created what he called a “castle cabinet”. His first stop was neighbour, industrialist, and inventor of jello, Peter Cooper. Cooper was intrigued by the project and said it offered the possibility of "a mighty power for the good of the world”.

Field obtained other crucial backers in Gisborne himself, the banker Moses Taylor, the shipowner Marshall Roberts and his long-term ally from the paper business Chandler White. These were all powerful men who could the financial value in urgent cross-Atlantic communication. The final member of his castle cabinet was Samuel Morse himself. Morse was feeling particularly vindicated as the US Supreme Court had just confirmed his sole patent of the electric telegraph.

On March 10, 1854, the cabinet agreed to take over Gisborne's company. They formed a new company called the New York, Newfoundland, and London Telegraph Company (N.Y.N.L.T.C., or given the difficult of remembering the initials called simply "the Company"). They managed to raise the extraordinary amount of $1.5 million in private funding for the project, an amount equal to roughly 2.5 percent of what was then the total expenditure of the US government. Yet this colossal amount wasn’t enough and Field was forced to travel many times to Britain to drum up more support.

By July 1857, all 2,500 nautical miles of the first transatlantic cable was manufactured and ready to load. No single ship could shoulder the entire load so the British and American navies provided one ship each carrying half a cable. They went to the middle of the Atlantic where their cables were spliced and set off in opposite directions. The USS Niagara was a modern ship and much faster than the ancient hulk of HMS Agamemnon. But it was the Niagara that hit trouble. It had laid 400 miles of cable when a huge wave struck and snapped the cable.

Field took this defeat in his stride and tried again twice in 1858. The second voyage failed again with a snapped cable. But the third time they got lucky. Once again it was the Niagara and the Agamemnon who faced off across the Atlantic. This time the cable held and the two ships successfully made shore. North America and Europe were linked.

This was an occasion of great, if shortlived joy. In August 1858 Field arranged for Queen Victoria to send the first transatlantic message to President James Buchanan. The Queen's 99 word message to Washington took almost 18 hours to transmit. Despite the slowness, New York erupted in celebrations, lauding Field, Morse, modern technology, and American ingenuity in general.

Compared to 2 weeks, 18 hours was a vast improvement. But it was still a work in progress. Field posed for Mathew Brady, who would achieve greatest success for his realistic Civil War photography. Brady added two key props for his portrait of Field - a length of wire cable and a globe.

But the cable would provide Field's undoing again. Victoria's message took too long to transmit and it was getting worse. The cable finally broke after three weeks. Celebration turned to anger. The Boston Courier newspaper suggested that the entire project had been part of an elaborate stock fraud and the cable had never worked. Their front page screamed a conspiracy theory headline: "Was the Atlantic cable a humbug?"

When the British cable in the Red Sea failed a year later, a committee of enquiry was asked to find out why underwater cables were humbug. Field and his electrician Dr Edward Whitehouse gave evidence. Serious problems emerged from the design of the cable. The cause was twofold. The first cause was the hastiness of the project due to Field’s relentless monomania, proving both a plus and a minus to the project. The second was Whitehouse’s excessive voltage to the cable. Whitehouse was trying to overcome the problem of low current which slowed down the operation.

Scottish physicist William Thomson solved that problem with his mirror galvanometer. The mirror galvanometer was a long distance receiver which could detect signals a thousand times fainter than other receivers.

But the cable project was put on hold for five years by the Civil War. A new attempt was undertaken in 1865 with much-improved material. This time just one ship was used to lay the cable, the massive SS Great Eastern designed by Brunel. New since Field last laid the cable, it was the largest steamship in the world. The Brunel completed the job in July 1866. The new connection was successful, more durable than before and many times faster. Even more public confidence resulted when a second cable was established shortly afterwards. The modern age had safely begun.

Field's finest hour would herald an astonishing downfall in his fortunes. With the profits from the Atlantic Cable company, Cyrus Field invested in New York’s elevated railroad. The railroads were successful, but Field was double-crossed by business partners, Jay Gould and his friend Russell Sage, who had well earned their nicknames of “robber barons”. Field suffered the ultimate indignity when his remaining fortune was stolen by his son. Field died in 1892, almost penniless.

But his cable had profound impact. It brought London and Wall St into each others sphere of instantaneous communication and influence. News and information could now spread quickly across the world from San Francisco to Singapore. Field is generally forgotten now and he remains relatively unknown but his transatlantic cable was one of the major birth pangs of the global village.
