Max Karl Ernst Ludwig Planck ( April 23, 1858October 4, 1947) was a German physicist who is considered to be the inventor of quantum theory.

Born in Kiel, Planck started his physics studies at Munich University in 1874, graduating in 1879 in Berlin. He returned to Munich in 1880 to teach at the university, and moved to Kiel in 1885. There he married Marie Mack in 1886. In 1889Events January-April January 8 Herman Hollerith receives a patent for his electric tabulating machine January 22 Columbia Phonograph is formed in Washington, DC. February 11 Meiji Constitution of Japan adopted; 1st Diet convenes in 1890 January 30 ? Crown, he moved to Berlin, where from 1892Events January 1 Ellis Island begins accepting immigrants to the United States. January 14 Death of Prince Albert Victor, Duke of Clarence, second in line heir to the throne of the United Kingdom of Great Britain and Ireland. Next in line is his younger b on he held the chair of theoretical physics.

In 1899Events January events January 1 End of Spanish rule in Cuba. January 1 Queens and Staten Island merge with New York City. January 3 The first known use of the word " automobile", in an editorial in the New York Times''. January 6 Lord Curzon becomes a vic, he discovered a new fundamental constant, which is named Planck's constant, and is, for example, used to calculate the energy of a photonFor the Japanese anime video, see Photon (anime). In physics, the photon (from Greek φοτος, meaning light is a quantum of excitation of the quantised electromagnetic field and is one of the elementary particles studied by qu. Also that year, he described his own setIn physics, Planck units are a system of units of measurement going back to Max Planck that is an early definition of natural units . The system is defined only using the following fundamental physical constants and is "natural" in the sense that the nume of units of measurement based on fundamental physical constantIn science, a physical constant is a physical quantity whose numerical value does not change. It can be contrasted with a mathematical constant, which is a fixed value that does not directly involve a physical measurement. There are many physical constants. One year later, he discovered the law of heat radiation, which is named Planck's law of black body radiationIn physics, the intensity spectrum of electromagnetic radiation from a black body at temperature T is given by the Planck's law of black body radiation : where: :ν is the frequency I ν) is the amount of energy per unit time per unit surface per unit. This law became the basis of quantum theory, which emerged ten years later in cooperation with Albert Einstein and Niels Bohr.

From 1905 to 1909, Planck acted as the head of the Deutsche Physikalische Gesellschaft (German Physical Society). His wife died in 1909, and one year later he married Marga von Hoesslin. In 1913, he became head of Berlin University. For the foundation of quantum physics, he was awarded the 1918 Nobel Prize in Physics. From 1930 to 1937, Planck was head of the Kaiser-Wilhelm-Gesellschaft zur Förderung der Wissenschaften (KWG, Emperor-Wilhelm-Society for the advancement of science).

During World War II, Planck tried to convince Hitler to spare Jewish scientists. Planck's son Erwin was executed on July 20, 1944, for treason in connection with an attempted assassination of Hitler. After Max Planck's death on October 4, 1947 in Göttingen, the KWG was renamed as the Max-Planck-Gesellschaft zur Förderung der Wissenschaften (MPG, Max-Planck-Society for the advancement of science).
