description: "Robert von Lieben was an Austrian entrepreneur, and self-taught physicist and inventor. Lieben and his associates Eugen Reisz and Siegmund Strauss invented and produced a gas-filled triode – the first thermionic valve with a control grid that was designed specifically for amplification rather than demodulation of signals, and is a distant ancestor of the thyratron. After Lieben's death, the \"Lieben valve\", which is also known in English as the \"Lieben-Reisz valve\" and in German as the \"LRS-Relais\", was used in the world's first continuous wave radio frequency generator designed for radio telephony."
