Nobel Prize physicist Planck was the founder of quantum theory. Aside from Albert Einstein, he laid the basis of modern physics.

The manuscript consisted of a few lines on one sheet of paper in which Planck summarised what is now known as Planck’s Law of radiation.

About Max Planck:
 

Planck made many substantial contributions to theoretical physics, but his fame as a physicist rests primarily on his role as the originator of quantum theory, which revolutionized human understanding of atomic and subatomic processes.

He is known for Planck's constant, which is of foundational importance for quantum physics, and which he used to derive a set of units, today called Planck units, expressed only in terms of fundamental physical constants.

Planck was twice president of the German scientific institution Kaiser Wilhelm Society. In 1948, it was renamed the Max Planck Society, Max-Planck-Gesellschaft, and nowadays includes 83 institutions representing a wide range of scientific directions.
