Dmitri Mendeleev is credited with developing the modern periodic table. Johann Wolfgang Dobereiner proposed the Law of Triads, an early attempt at classification. John Newlands proposed the Law of Octaves, another early attempt. Robert Bunsen was a chemist famous for inventing the Bunsen burner and his work in spectroscopy, which led to the discovery of elements like Cesium and Rubidium, but his main contribution was not to the theory or system of periodic classification itself.
