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.

He wrote a book on Johann Dobereiner, a German chemist. Goehte was his best friend.
Johann Wolfgang Döbereiner discovered the concept of the law of triads in 1817.
Dobereiner gave triads for few elements. It could not be applied to other elements.So it was not considered further.
Johann Dobereiner grouped elements with similar properties into triads. In these triads, he observed that the properties of the middle element were the average of the other two.
Because he was a good scientist
