Max Planck, Inventor of Quantum Theory > 
Max Karl Ernst Ludwig Planck was a German physicist who is considered to be the inventor of quantum theory. In 1899, he discovered a new fundamental constant, which is named Planck's constant, and is, for example, used to calculate the energy of a photon. Also that year, he described his own set of units of measurement based on fundamental physical constants. One year later, he discovered the law of heat radiation, which is named Planck's law of black body radiation. This law became the basis of quantum theory, which emerged ten years later in cooperation with Albert Einstein and Niels Bohr.
