The correct answer is "Samuel Morse."
The individual that I think created the invention with the greatest impact on the nation's development was Samuel Morse.
The reason why is that Samuel Morse (1791-1872) was the inventor of the Telegraph. In 1832, Alfraid Veil served as the investor of the project that Morsoe developed, and that resulted in the invention of a system that used wires to transmit dots and dashes that have to be interpreted to be understood. That was the Morse code.
In 1842, Morse received the support of US Congress to built a telegraph line from Washington D.C to Baltimore., Maryland. The first full message transmitted through this 38-mile line was done on My 24 1844.
From then on, long-distance communications would never be the same.
Morse revolutionized communications not only in the US but in all the world.
