Max Planck is well known for working on thermodynamics. He acquired his interest on the subject after his studies under Gustav Kirchhoff, whom he greatly admired. Planck was later called the father of quantum physics after he gave the world his incredible Plancks constant. Because of Planck, later developments in quantum physics were made by Albert Einstein, Neils Bohr, and Erwin Schrodinger.

Max Karl Ernst Ludwig Planck (Max Planck) was born in Kiel, Germany in April 1858. Planck studied at the Universities of Munich and Berlin, where his teachers included Kirchhoff and Hermann von Helmholtz. He received his doctorate of philosophy at Munich in 1879. He was Privatdozent in Munich from 1880 to 1885, then Associate Professor of Theoretical Physics at Kiel until 1889, in which year he succeeded Kirchhoff as Professor at Berlin University, where he remained until his retirement in 1926. Afterwards, he became President of the Kaiser Wilhelm Society for the Promotion of Science, a post he held until 1937. The Prussian Academy of Sciences appointed him a member in 1894 and Permanent Secretary in 1912. He later published papers on entropy, thermoelectricity, and the theory of dilute solutions.

Planck is best known as the originator of the quantum theory of energy for which he was awarded the Nobel Prize in 1918. His work contributed significantly to the understanding of atomic and subatomic processes. He died of a heart attack in Göttingen, Germany on October 4, 1947.
