Paul Julius Reuter founds a media empire.
A German born immigrant, Paul Julius Reuter arrives in London from Aachen where he has been running a news and stock price information service. Using a combination of technologies – including telegraph cables and a fleet of carrier pigeons that grows to exceed 200 – Reuter establishes an enviable reputation for speed, accuracy, integrity and impartiality.

Reuter opens 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.
