Abraham Niclas Edelcrantz (bornClewberg; 28 July 1754 – 15 March 1821) was a Finnish-born Swedish poet and inventor. He was a member of theSwedish Academy, chair 2, from 1786 to 1821.
Edelcrantz was the librarian atThe Royal Academy of Turku. In 1783 he moved to Stockholm to lead the Royal Theater and later work as the private secretary of the kingGustaf III.[1] He is known for his experiment with theoptical telegraph. He inaugurated his telegraph with a poem dedicated to the Swedish King on his birthday in 1794. The message went from the Palace inStockholm to the King atDrottningholm.
He eventually developed his own system which was quite different from its French counterpart and almost twice as fast. His system was based on ten collapsible iron shutters. The several positions of the shutters formed combinations of numbers which were translated into letters, words or phrases via codebooks. The telegraph network was made up of telegraph stations positioned at about 10 kilometres from one another.
In 1796 he wroteA Treatise on Telegraphs.
In 1797, he was elected a member of theRoyal Swedish Academy of Sciences.
