Michael Esposito (paranormal investigator)
Michael Andrew Esposito was born in Gary, Indiana in 1964. He is a descendant of Alfred Vail who invented the Morse Code and several early telegraph devices with his partner Samuel Morse. The invention of the telegraph sparked the spiritualist movement of the middle 1800s and the telegraph was used in spirit communication. Another ancestor, Jonathan Harned Vail was office manager and assistant to Thomas Edison. Edison, in his later years attempted to develop a device for communicating with the dead. Michael studied communication theory at Purdue University, University of Notre Dame, American University in Cairo, Egypt and Governor's State University. During the Gulf War Michael was a Psy-ops officer in Iraq.
Electrical telegraph
The first system that didn't require skilled technicians to operate, was Charles Wheatstone's ABC system in 1840 where the letters of the alphabet were arranged around a clock-face, and the signal caused a needle to indicate the letter. This early system required the receiver to be present in real time to record the message and it reached speeds of up to 15 words a minute.
