Map showing the Telegraph Lines
in operation, under contract, and contemplated, to complete the circuit
of the Globe.
Samuel Morse (1791-1872), a well-known portrait painter by trade, began his quest for an easier and more economical communication solution in the 1830's as newly realized electromagnetism was being talked about through much of the world.
Although a multiple-wire electromagnetic telegraph system was introduced in 1833, Morse took it one step further, developing a single wire system which could signal over a much longer distance and allowed operators to engage electrical current using a single key. His less costly system was adopted quickly by railroads and other businesses.
The discovery also led him to develop the popular Morse Code, which became the universal language of the telegraph and is still in use today.
On June 10 in the year of this map’s publishing, a bronze statue of Samuel Morse was introduced in New York City’s Central Park.
This relief map was published in 1871 by G.W. & C.B. Colton and Co. It notes key cities, rivers, telegraph lines, and major ocean explorations.
