A major breakthrough was made by Max Planck who made a formula that agreed with experimental data, which is showed above. However, he had major problems proving this law. His idea was that the oscillating electrons of the surface atoms of the black body emitted radiation according to Maxwell's laws of electromagnetism.

In December 1900 Max Karl Ernst Ludwig Planck (1858 Apr 23 - 1947 Oct 04) revealed to the scientific community what he had worked out in October and presented to the German Physical Society in a lecture - the formula accurately describing the distribution of energy over the frequencies comprising blackbody radiation.
