On this date in 1971, Henry Sampson, an African American inventor, received a patent for his work related to the cellular phone. He is credited with inventing the gamma-electric cell, a technology that was key in the development of the modern cellular phone. Sampson’s invention helped lay the groundwork for the mobile communication systems we use today.
While Martin Cooper of Motorola is often credited with making the first mobile phone call in 1973, Sampson’s contribution was an essential piece of the technological puzzle, particularly in how signals are transmitted wirelessly.
