János Irinyi (sometimes also spelled János Irínyi; Hungarian pronunciation: [ˈjaːnoʃ ˈiriɲi]; 18 May 1817 – 17 December 1895) was a Hungarian chemist and inventor of the noiseless and non-explosive match. He achieved this by mixing the yellow (also called white) phosphorus with lead dioxide instead of the potassium chlorate used previously.[1]
Irinyi also took part in the Hungarian Revolution of 1848.[2]
