Queen Victoria telegraphed US PresidentIn 1858, Queen Victoria sent the first official telegraph message across the Atlantic Ocean from London to the US. (Test messages had been exchanged for 10 days). Her message to President Buchanan, in Washington DC, began transmission at 10:50am and was completed at 4:30am the next day, taking nearly 18-hrs to reach Newfoundland. With 99 words, consisting of 509 letters, it averaged about 2-min per letter. The message was forwarded across Newfoundland by an overhead wire supported on poles; across Cabot Strait by submarine cable to Aspy Bay (Dingwall), Cape Breton; and by an overhead wire across eastern Canada and Maine, via Boston to New York. This earliest Transatlantic cable went dead within a month. |
