First successful phone call (March 10, 1876)
Before the internet we had the phone. Well, we still do, but let's be honest, most of us carry our cell phones around because they can get us online anywhere we are. But up to the internet, the phone was probably the most transformative communication technology the world has ever seen. And on March 1
Bell, as his father before him, spent much of his career studying speech and voice and becoming a professor of vocal physiology at Boston University in 1873. He eventually spent working on a system to transmit over a telegraph-like system. build what would be the phone with engineer Thomas Watson. In June 1875, Bell and Watson transmitted sound vibrations between two receivers – no understandable words were heard, but human sounds were heard at the receiver end.
In March 1876, the system had improved enough for Bell to think it could transmit full speech. He had also filed a patent for his system, which was awarded only three days before the successful March 10 test. Less than six months later, Bell tested his invention with a call placed over a two-mile distance. Of course, it is still far from the instantaneous worldwide communication that the phone is offering now, but it was still a landmark development.
