Henry T. Sampson in 1971? No!
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.
Richard Spikes in 1932? No!
The first automatic-transmission automobile to enter the market was designed by the Sturtevant brothers of Massachusetts in 1904. US Patent #766551 was the first of several patents on their gearshift mechanism. Automatic transmission technology continued to develop, spawning hundreds of patents and numerous experimental units; but because of cost, reliability issues and an initial lack of demand, several decades passed before vehicles with automatic transmission became common on the roads.
