(106869) Irinyi Main-belt Asteroid
Discovered on 31 December 2000 by Sarneczky, K., Kiss, L. at Piszkesteto.
János Irinyi (1817-1895) invented the “noiseless” match. An unsuccessful experiment in 1836 at the Vienna Polytechnikum gave him the idea that by replacing potassium chlorate with lead dioxide a non-explosive match can be created. After returning home he founded the first factories for such matches in Pest.Naming citation (20080122/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
