The Patent Hidden Behind the Myth
Archivists use portraits, patent drawings, and technical language to measure Tesla's real engineering against a century of larger claims.

A legend can glow; a patent drawing must show exactly what an inventor built.
At the National Archives, one motor drawing sits among about 1,000,000 utility-patent drawings.
The collection has Napoleon Sarony's portrait, preserved as a small glass negative.
Tesla was a Serbian-American engineer and physicist, born 1856, dead 1943.
He came to the United States in 1884 and began at Edison’s lab.
Edison employed him at the Machine Works. Tesla later became a U.S. citizen.
In 1886, Tesla formed Tesla Electric Light and Manufacturing.
In 1888, Tesla invented the first usable alternating-current motor.
The National Archives holds a Tesla patent drawing for an electric motor.
A later motor patent described one line circuit replacing two via the motor’s inductive relations.
Chicago’s 1893 World’s Fair showed alternating-current generators.
Contemporaries tied Tesla’s ideas to progress in electrical power engineering and radio.
Tesla designed the first Niagara Falls hydroelectric plant to harness the Falls’ energy.
The paper feels cold; behind each line stands a human ambition to control power.
In 1915, Tesla said his circuits could resist static, interference, nearby lightning.
Tesla's 1915 patent claim targeted receivers facing electrical noise.
That same era brought Tesla’s claim: his receiver heard radio communications from Mars.
The press reported it broadly, while scientists showed little serious interest.
Decades later, radio telescopes turned electromagnetic waves into heavenly data.
In the 1960s, scientists began seeking intelligent-life signals elsewhere.
Where it leaves off
Tesla's patents documented what he could build, but new instruments would soon test whether the heavens could truly speak by radio.
