1 The History of Morse Code From the Railroad Telegraphers to the Wireless Ops 1
2 Samuel Morse, inventor 1836 Samuel Morse invents electric telegraph able to send messages up to 500 yards! 1842 Morse erects circuit between Wash. DC and Baltimore 38 miles; few interested 1844 Sends What God hath wrought to Capitol 1845 Forms the Magnetic Telegraph Company 1847 Received patent for electric telegraph 1847 Patent contested; built telegraph in Europe Paid $80,000; Netherlands to Turkey 1853 Invention upheld by U.S. Supreme Court 1872 Samuel Morse dies, 80 years old 2
3 Early American Telegraph Companies 1851 New York Telegraph Co. formed; lines from New York City to Boston & St. Louis. Based on Morse's success in Europe 1852 Dozens of other local companies formed but very limited due to no long lines 1854 Samuel Morse returns to United States 1856 New York Telegraph Co. buys up most local companies; renamed Western Union 1861 Western Union completes lines from Omaha to Sacramento coast-to-coast 1869 Transcontinental Railroad completed 3
4 Stringing the Line to Sacramento Western Union formed 1861 telegraph lines spanned the continent 4
5 Early Development 1861 Telegraph/Western Union becomes huge asset to Union Army during Civil War 1865 Western Union enters agreement with the railroads to share lines 1880s Railroads arrive in NM, TX, AZ; railroad & Western Union lines connect army forts for communications & the Indian Wars 1886 Geronimo, Nana, Naiche (son of Cochise), Mangas, etc. surrender at Skeleton Canyon 5
6 1880 Victorio Killed at Tres Castillos Mexico Telegraphed to Washington DC but not believed 6
7 1886 Geronimo Surrenders Nana, Natchez (Son of Cochise), Mangas, etc. Geronimo party at Socorro train depot enroute to Florida
8 Railroad and Western Union Telegraph Relay Stations Railroad telegraphers fastest growing career in America s 8
9 The main job of the railroad telegrapher was keeping track of trains and rolling stock between stations or the main lines 9
10 Dozens of Train Orders were sent daily to track regular train movements and Extras 10
11 A missed Train Order... 11
12 ... wasn't pretty!!! 12
