Samuel F.B. Morse's invention of the telegraph marked a new era in communication. For the first time, people were able to communicate quickly from great distances. The genesis of Morse's invention is covered in detail, starting in 1832, along with the establishment of the first transcontinental telegraph line in the United States and the dramatic effect the device had on the Civil War. The Morse telegraph that served the world for over 100 years is explained in clear terms. Also examined are recent advances in telegraph technology and its continued impact on communication.
