Max Karl Ernst Ludwig Planck

Planck starts his physics studies at [[München]] university in 1874, and graduates 1879 in Berlin. He returns to München in 1880 to teach at the university, and moves to Kiel? in 1885. There, he marries Marie Merck in 1886. In 1889, he moves to Berlin, where from 1892 on he holds the chair of theoretical physics.

In 1899, he discoveres a new fundamental constant, which is named [Planck's constant]?, and is, for example, used to calculate the energy of a photon. One year later, he discoveres the law of heat radiation, which is named [Planck's Law of Radiation]?. This law becomes the basis of quantum theory, which emerges ten years later in cooperation with Albert Einstein and Niels Bohr.

From 1905 to 1909, Planck acts as the head of the Deutsche Physikalische Gesellschaft (German Physical Society). His wife dies in 1909, and only one year later, he marries Marga von Hoesslin. In 1913, he becomes head of Berlin university. For the foundation of quantum physics, he is awarded the 1918 Nobel Prize in physics. From 1930 to 1937, Planck becomes head of the Kaiser-Wilhelm-Gesellschaft zur Förderung der Wissenschaften (KWG).

During World War II, Planck tries to convince Hitler to spare Jewish scientists. Planck's son Erwin is executed on Juli 20, 1944, for treason in connection with an attempted assasination of Hitler. After Max Planck's death in 1947, the KWG is renamed into [Max-Planck-Gesellschaft zur Förderung der Wissenschaften] (MPG).
