Before the first silicon chip or the Moog synthesizer, there was Lev Sergeyevich Termen. To the world, he was the musical pioneer behind the Theremin, the world’s first gesture-controlled instrument. To the Kremlin, he was a high-level asset who engineered the "Great Seal Bug"—a passive, zero-power listening device that eluded U.S. detection for seven years by exploiting the very laws of physics. This talk will dive into the life of the ultimate hardware hacker. It will deconstruct the "Ether Music" that birthed electronic synthesis, revealing how Termen turned the human body into a variable capacitor to "play the air." But I’ll go deeper than the music: Termen’s true obsession wasn't just audio—it was persistence. A firm believer in transhumanism long before the term existed, Termen viewed the human body as a legacy system plagued by a "death bug." We’ll explore his clandestine work in Soviet sharashkas and his radical foray into cryogenics, where he sought to "freeze" life to wait for a future technological patch. The talk will include audio clips maybe some quick demos of theremins!
