Léon Theremin Inventor
Lev Sergeyevich Termen; Russian: Ле́в Серге́евич Терме́н) (27 August [O.S. 15 August] 1896 – 3 November 1993 (Léon Theremin in America) was a Russian and Soviet inventor. He is most famous for his invention of the theremin, one of the first electronic musical instruments, and the first to be mass produced. He is also the inventor of interlace, a technique of improving the picture quality of a video signal, widely used in video and television technology. His invention of "The Thing", an espionage tool, is considered a predecessor of RFID technology. Léon Theremin was born Lev Sergeyevich Termen in Saint Petersburg, Russian Empire in 1896 into a family of French and German ancestry. He had a sister named Helena. He started to be interested in electricity at the age of 7, and by 13 he was experimenting with high frequency circuits. In the seventh class of his high school before an audience of students and parents he demonstrated various optical effects using electricity. By the age of 17 he was in his last year of high school and at home he had his own laboratory for experimenting with high frequency circuits, optics and magnetic fields.

The terpsitone was an electronic musical instrument, invented by Léon Theremin, which consisted of a platform fitted with space-controlling antennae, through and around which a dancer would control the musical performance. By most accounts, the instrument was nearly impossible to control. Of the three instruments built, only the last one, made by Theremin in 1978 for Lydia Kavina, survives today. The instrument was named after the Greek muse of dance, Terpsichore.
3.Thing Passive cavity resonator||Great Seal bug
The Thing, also known as the Great Seal bug, was one of the first covert listening devices to use passive techniques to transmit an audio signal. Because it was passive, being energized and activated by electromagnetic energy from an outside source, it is considered a predecessor of RFID technology.
