About Dr. Moses Greeley Parker

Dr. Moses Greeley Parker was an incredible man! Among his many accomplishments, he was the first to photograph the tubercular bacillus; the first to photograph electric currents and to show they take the form of spirals (this meant that if telephone wires were spiraled messages could be sent over longer distances); and he also is credited with inventing the telephone directory system – so you can thank Moses Greeley for your telephone number!!
