János Irinyi (Hungarian pronunciation: [ˈjaːnoʃ ˈiriɲi]; sometimes also spelled János Irínyi; Romanian: Ioan Irinyi; 18 May 1817, in Albis [Romanian: Buduslau] – 17 December 1895, in Vértes (today Létavértes - Hungary) was a Hungarian chemist and inventor of the noiseless and non-explosive match. He achieved this by mixing the phosphorus with lead dioxide instead of the potassium chlorate used previously.
Asteroid 106869 Irinyi, discovered by Hungarian astronomer Krisztián Sárneczky and László L. Kiss at Piszkéstető Station in 2000, was named in his memory. The official naming citation was published by the Minor Planet Center on 22 January 2008 (M.P.C. 61767).
- Hungarian Patent Office; this site's mention of calcium chlorate rather than potassium chlorate appears to be an error?
