Max Planck (died 1947) introduced the supposition that electromagnetic energy could be emitted only in quantized form. In other words, the energy could only be a multiple of an elementary unit (E = hv, where h is Planck's constant and v is the frequency of the radiation).

At first, Planck considered that the quantisation was only "a purely formal assumption" (useful only in logic, not in reality). Nowadays this assumption, incompatible with classical physics, is regarded as the birth of quantum physics and the greatest intellectual accomplishment of Planck's career. It was in recognition of his monumental accomplishment that Planck was awarded the Nobel Prize in Physics in 1918.

The discovery of Planck's constant enabled him to define a new universal set of physical units, such as the Planck length and the Planck mass, all based on fundamental physical constants.

Subsequently, Planck tried to align his findings with classical physics but to no avail. Even several years later, other physicists set Planck's constant to zero in order to align his findings with classical physics, but Planck knew well that this constant has a precise nonzero value. "I am unable to understand Jeans' stubbornness he is an example of a theoretician as should never be existing."
