Uchida Hideo, the man who invented the transistor a year before William Bradford Sockly

In 1947, Hideo Uchida of the NHK Science & Technical Research Laboratories completed an amplifier circuit (tripolar crystal) that would be the base of the transistor. 

However, his superior didn’t understand him and it ended unpublished as the magazine editor to whom Uchida delivered the contents of his research, leaked it to GHQ and it became the subject of censorship. 

After half a year, Sockly announced his invention. He discovered that when the Americans test-detonated a new atomic bomb, this could be detected because it immediately caused little white dots to appear on a television screen.

However, at the time, the former Japanese army thought that this would cause a deterioration of troop morale and they suppressed the announcement.
