He developed the Planckian distribution law, which accurately describes the spectrum of electromagnetic radiation emitted by a black body in thermal equilibrium, fitting experimental data across all wavelengths.
He served as president of the Kaiser Wilhelm Society (1930–1937), which was renamed the Max Planck Society in 1948. Max Planck
Max Planck (1858–1947) was a German theoretical physicist best known as the , a discovery that earned him the 1918 Nobel Prize in Physics. His work fundamentally transformed 20th-century physics by introducing the concept that energy is quantized, or emitted in discrete packets.
