International Meridian Conference
On 11 October 1883, a convention of railroad executives met in Chicago and agreed to the implementation of five time zones in North America, using as a basis Greenwich Mean Time. Before the invitations to the Washington conference were sent out on December 1, the joint efforts of Abbe, Fleming and William Frederick Allen, Secretary of the US railways' "General Time Convention" and Managing Editor of the "Travellers' Official Guide to the Railways", had brought the US railway companies to an agreement which led to standard railway time being introduced at noon on 18 November 1883 across the nation. Although this was not legally established until 1918, there was thus a strong sense of "fait accompli" that preceded the Washington conference, although setting local times was not part of the remit of the conference.
Naming of the Americas
The earliest known use of the name "America" dates to April 25, 1507, where it was applied to what is now known as South America. It appears on a small globe map with twelve time zones, together with the largest wall map made to date, both created by the German cartographer Martin Waldseemüller in Saint-Dié-des-Vosges in France. These were the first maps to show the Americas as a land mass separate from Asia. An accompanying book, "Cosmographiae Introductio", anonymous but apparently written by Waldseemüller's collaborator Matthias Ringmann, states, "I do not see what right any one would have to object to calling this part [that is, the South American mainland], after Americus who discovered it and who is a man of intelligence, Amerigen, that is, the Land of Americus, or America: since both Europa and Asia got their names from women".
