Johann Wolfgang Döbereiner was a German chemist known for his work in the early 19th century, particularly for formulating the concept of triads. He discovered that certain groups of three elements with similar properties could be arranged in a way where the atomic weight of the middle element was approximately the average of the other two. This led to the development of the periodic classification of elements and laid the groundwork for later periodic tables. His work highlighted patterns in elemental properties, contributing significantly to the field of chemistry.
