Hanso Schotanus á Steringa Idzerda (26 September 1885 – 2 November 1944) was a Dutch scientist, entrepreneur and pioneer in radio technology.^[1]

Idzerda in 1919

Between 1907 and 1917 he worked to introduce the already invented triode into radio technology.^[1] In 1919 Idzerda invented the triode IDZ-lamp, which was capable of transmitting and receiving radio messages containing the human voice.^[1] On 6 November 1919 he held the first public airing of a radio programme.^[1] His programme consisted of music, and him talking for a bit in between pieces.^[1] The PCGG transmitter he personally invented was capable of transmitting signals from The Hague all the way to England.^[1] Herman de Man, later to be an important author and radio maker, was present.^[1] From then on the programme aired every week. In 1922 the Daily Mail decided to sponsor Idzerda, who previously financed the operation with his own money and some donations.^[1] After the Daily Mail ceased its support Idzerda's company went bankrupt.^[1]

On 2 November 1944, a V-2 rocket that was being testing close to his house crashed and Idzerda decided to take a look.^[1] He was ordered to leave the area but later snuck back to the rocket and was promptly executed.^[1]
