USA SAMUEL F. B. MORSE
Samuel Morse, 1845, in daguerreotype. In the US, he was generally accepted as the electric telegraph's inventor. After 1844 telegraph use expanded rapidly, with 12,000 miles of wire strung across the US, Morse fought to hold the patent on his telegraph. Finally, in 1853, the Supreme Court supported him as the inventor of the 'repeater circuit', which boosted the signal as it ran through the wires. But he was not granted a patent monopoly for 'for any and all use of the electromagnetic force for purposes of transmitting intelligible signals to any distance' (BSLOC_2019_7_82) (KEYSTONE/Everett Collection/)
