You’d better not ignore Russian Prior Art search – says New Scientist magazine

LED developed in Russia in 1920s

CLAIMS THAT the LED was invented by four independent American research groups in 1962 are false, according to New Scientist magazine.

The mag’s hacks have found that the LED was invented by a Russian genius around forty years earlier.

Oleg Vladimirovich Losev was a radio technician who noticed that diodes used in radio receivers emitted light when current was passed through them. In 1927, he published details in a Russian journal of the first ever LED.

Details of Losev’s invention have been dug up by Nikolay Zheludev, at the University of Southampton.

It is not as if the discoveries were locked in Russia and never escaped. Losev also published on his discoveries in German and British journals where they were ignored. More than sixteen papers written between 1924 and 1930 he comprehensively detailed the function of his LED.

He used Einstein’s quantum theory to explain the way electrons dropping in energy produced the light without releasing heat. When he wrote to the man himself, but Einstein didn’t reply. In 1927 he Losev filed a patent for a ‘light relay’ that used his devices ‘for fast telegraphic and telephone communication, transmission of images and other applications…’ None of his work was picked up and Losev died of hunger in 1942 during the siege of Leningrad (aka St.Petersburg), at the age of 39.

Zheludev discovered that in November 1941, Losev tried to get a paper based on a discovery that using semiconductors, a three-terminal system may be constructed analogous to a vacuum triode. Zheludev thinks that he may have invented the transistor.

  1. May the starving American Engineers be supported in their inventions, until they become rich and famous, commensurately with their IP contributions. This will help, maintain, and grow USA GDP above 14T$. Think of our children and gross national debt. Thank you!
