Johann Wolfgang Döbereiner (1780-1849), a German chemist known for his discovery in 1829 of similar triads of elements, a key step in the development of the periodic law. This directly led to the periodic table of the chemical elements, the arrangement of known chemical elements by electron structure so that certain chemical properties vary regularly across the table. Döbereiner discovered furfural, worked on the use of platinum as a catalyst, and invented a lighter (known as Döbereiner's lamp) that is ignited by the action of hydrogen on a platinum sponge.
