Morse sends 'What hath God wrought'

24 May 1844

On 24 May 1844 Samuel Morse, seated in the Supreme Court chamber in the Capitol in Washington, tapped out the message 'What hath God wrought' in his code of dots and dashes, which was received at a railway depot in Baltimore 60 km away by his assistant Alfred Vail. The electric telegraph, built on the work of Joseph Henry and others, spread rapidly across the world: the first transatlantic cable was laid in 1858, and the first permanent one in 1866. For the first time, news could travel faster than a messenger, and it changed business, journalism and war.
