“At first no one believed Edison when he said he'd made an electric bulb. They dismissed it as a filament of his imagination.”
Telegraph registerIn 1849, a telegraph register was patented by Samuel F. B.Morse (No. 6,420). Although Morse first thoughts of an electromagnetic telegraph (1832) led to building an experimental version (1835), he constructed his first truly practical system in 1844. That line ran from Baltimore to Washington, DC. This patent incorporates the basic features of the 1844 receiver and a method for marking dots and dashes on paper. Within ten years after the first telegraph line opened, 23,000 miles of wire crisscrossed the country. The invention profoundly affected the development of the West, made railroad travel safer, and allowed businessmen to conduct their operations more profitably. |
