106869 Irinyi           Discovered 2000 Dec. 31 by K. Sárneczky and L. Kiss at Piszkéstető.
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.
