9698 Idzerda           Discovered 1971 Mar. 25 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Hanso Henricus Schotanus Steringa Idzerda (1885-1944) invented the vacuum triode for amplifying audio and radio signals. In November 1919 he started the first radio broadcasting station in the world from The Hague.
