John Pierce invented the first communications satellite. In 1936,
Pierce joined Bell Telephone Laboratories and helped develop the
traveling wave tube, an amplifier that facilitates satellite communication.
He then began advocating the use of unmanned passive and active
communication satellites, eventually convincing NASA to build
a satellite based on his design. In 1960, NASA launched Echo 1,
an aluminum-coated balloon that was 100-feet in diameter and bounced
radio waves from one ground-based station to another. Following
the success of Echo 1, Telstar 1 was launched in 1962. This first
commercial communications satellite was in low-orbit and transmitted
the first live television signals across the Atlantic.
