Henry Thomas Sampson Jr. (April 22, 1934 – June 4, 2015) was an American engineer, inventor and film historian [1] who created the gamma-electric cell in 1971 — a device with the main goal of generating auxiliary power from the shielding of a nuclear reactor.
In 1970, Amos E. Joel, Jr., a Bell Labs engineer, [22] invented a "three-sided trunk circuit" to aid in the "call handoff" process from one cell to another. His patent contained an early description of the Bell Labs cellular concept, but as switching systems became faster, such a circuit became unnecessary and was never implemented in a system.
1971: AT&T submitted a proposal for cellular phone service to the U.S. Federal Communications Commission (FCC). 3 April 1973: Motorola employee Martin Cooper placed the first hand-held cell phone call to Joel Engel, head of research at AT&T's Bell Labs, while talking on the first Motorola DynaTAC prototype.

Alexander Graham Bell was a professor of elocution at Boston University and tutor of deaf children. He had begun electrical experiments in Scotland in 1867 and, after emigrating to Boston from Canada, pursued research into a method of telegraphy that could transmit multiple messages over a single wire simultaneously, a so-called "harmonic telegraph".
W. Rae Young in 2006. William Rae Young, Jr. (October 30, 1915 – March 7, 2008) was one of the Bell Labs engineers that invented the cell phone. The history of cellular phone technology began on December 11, 1947 with a Bell Labs internal memo written by Douglas H. Ring describing the idea of Rae Young of the hexagonal cell concept for a cellular mobile telephone system.
In December 1947, Bell Labs engineers Douglas H. Ring and W. Rae Young proposed hexagonal cell transmissions for mobile phones. [38] Philip T. Porter, also of Bell Labs, proposed that the cell towers be at the corners of the hexagons rather than the centers and have directional antennas that would transmit/receive in 3 directions (see picture ...
