According to http://inventors.about.com/library/weekly/aa070899.htm the inventors of the Radio telephone system, the modern cell phone, was a man named Dr. Martin Cooper. Other inventors include, Richard W. Dronsuth, Albert J. Mikulski, Charles N. Lynk Jr. James J. Mikulski, John F. Mitchell, Roy A. Richardson, and John H. Sangster. Cooper made the first call on a portable cell phone in April 1973. He made that call to his rival, Joel Engel. Bell Laboratories introduced the idea of cellular communications in 1947 with the police car technology. Motorola was the first to incorporate the technology into portable device that was designed for use outside of a automobile.

Henry Thomas Sampson, Jr. (born in Jackson, Mississippi in 1934) is an American inventor.

He graduated from high school in 1951 from Lanier High School in Jackson, Mississippi. He then attended Morehouse College for a couple of years before transferring to Purdue University. He received a Bachelor's degree in science from Purdue University in 1956. He graduated with an MS degree in engineering from the University of California in 1961. Sampson also received his MS in Nuclear Engineering from the University of Illinois Urbana-Champaign in 1965, and his PhD in 1967.

He is the first African American to earn a Ph.D.in Nuclear Engineering in the United States. Some of his accomplishments include being a member of the United States Navy between the years 1962 and 1964 and earning an Atomic Energy Commission honor between 1964 and 1967. Later he was awarded the Black Image Award from Aerospace Corporation in 1982. He was awarded the Blacks in Engineering, Applied Science Award, and prize for education, by the Los Angeles Council of Black Professional Engineers in 1983. In June 2007, Sampson was married to Laura Howzell Young in St. Thomas, U.S. Virgin Islands. Young-Sampson is a professor in the College of Education at California State University San Bernardino.

Sampson was employed as a research chemical engineer at the U.S. Naval Weapons Center, China Lake, California, in the area of high energy solid propellants and case bonding materials for solid rocket motors. Sampson also served as the Director of Mission Development and Operations of the Space Test Program at the Aerospace Corporation in El Segundo, California.

His patents included a binder system for propellants and explosives and a case bonding system for cast composite propellants. Both inventions are related to solid rocket motors. He received a patent, with George H. Miley, for a gamma-electrical cell on July 6, 1971.

On July 6, 1971, Sampson was awarded a patent for the "gamma-electric cell". The gamma-electric cell is a device that produces a high voltage from radiation sources, primarily gamma radiation, with proposed goals of generating auxiliary power from the shielding of a nuclear reactor. Additionally, the patent cites the cell's function as a detector with self power and construction cost advantages over previous detectors.

He never even made the cell phone. On July 6, 1971, Sampson and co-inventor George Miley received a patent on a "gamma electric cell" that converted a gamma ray input into an electrical output (Among the first to do that was Bernhard Gross, US patent #3122640, 1964). What, you ask, does gamma radiation have to do with cellular communications technology? The answer: nothing. Some multiculturalist pseudo-historian must have seen the words "electric" and "cell" and thought "cell phone."The father of the cell phone is Martin Cooper who first demonstrated the technology in 1973.
