On April 3rd, 1973, Motorola engineer Marty Cooper placed the first public call from a cellphone according to the Verge. In midtown Manhattan, Cooper called Joel Engel — head of rival research department Bell Labs — saying “Joel, this is Marty. I’m calling you from a cell phone, a real handheld portable cell phone.” The call was placed on a Motorola DynaTAC 8000x, which weighed 2.5 pounds, a far cry from today’s 4-ounce handsets.
If it wasn’t for Dr. Henry T. Sampson we wouldn’t have cell phone technology today. Isn’t it funny how the mainstream media hasn’t made him a icon based off of his invention? Cellular telephony has spawned a Multi-billion dollar industry and has freed tens of millions of people, both at home and at work, to communicate anywhere, any time. I would of thought he would on the Times and Forbes magazines next to Bill Gate and Steve Jobs for discovering one of the greatest creations of our time.
Born in Jackson, Mississippi, he received a Bachelor of Science degree from Purdue University in 1956. He went on to the University of California, Los Angeles where he graduated with an MS degree in engineering in 1961; University of Illinois Urbana-Champaign, MS in Nuclear Engineering in 1965, and a PHD in 1967.
Mobile Communications took a big step forward in 1983 with the invention of the Cellular System regulating the portable telephones, which use radio waves to transmit and receive audio signals. Before this time, mobile telephone service in the United States, consisting mainly of car phones, was extremely limited because metropolitan areas had only one antenna for these purposes. In addition, the Federal Communications Commission (FCC) assigned only 12 to 24 frequencies to each area, which meant that only that many calls could occur at a time. These limitations often meant a wait of up to 30 minutes for a dial tone and a five to 10 year waiting list just to acquire the service. With the invention of cellular phone service in 1983, personal communications no longer depended on wires. In the 1990s it would become possible to connect to the Internet from virtually anywhere in the world using a portable computer and a cellular modem with satellite service. Technologies that developed from different fields, such as personal communications, computation, and space exploration often worked together to serve the constantly evolving human needs of the information age.
Henry T. Sampson worked as a research Chemical Engineer at the US Naval Weapons Center, China Lake, California. 1956-61. Henry T. Sampson then moved on to the Aerospace Corp, El Segundo, California. His ti*les include: Project Engineer, 1967-81, director of Planning and Operations Directorate of Space Test Program, 1981-, and Co-inventor of gamma-electric cell. He holds patents related to solid rocket motors and conversion of nuclear energy into electricity. He also pioneered a study of internal ballistics of solid rocket motors using high-speed photography. He was also a producer of docu*entary films on early black filmmakers and films, a member of the board of directors of Los Angeles Southwest College Foundation, and a technical consultant to Historical Black Colleges and Universities Program.
