In 1851, Reuter moved to London. After failures in 1847 and 1850, attempts by the Submarine Telegraph Company to lay an undersea telegraph cable across the English Channel, from Dover to Calais, promised success.
Reuter set up his "Submarine Telegraph" office in October 1851 just before the opening of that undersea cable in November, and he negotiated a contract with the London Stock Exchange to provide stock prices from exchanges in continental Europe in return for access to the London prices, which he then supplied to stockbrokers in Paris.
