In 1851 Reuter opened an office with the help of an 11 year-old office boy at 1 Royal Exchange Building in London's financial centre, located close to the main telegraph offices. Using his "telegraph expertise," he transmits stock market quotations and news between London and Paris over the new Dover-Calais submarine telegraph cable.
