Max Planck, known as the Father of Quantum Theory, was born on April 23, 1858, in Kiel, which was part of the German Confederation at the time. Coming from an intellectual family, he was the sixth child of Johann Julius Wilhelm Planck and Emma Patzig. His father taught law at the University of Kiel, and both his grandfather and great-grandfather were theology professors in Göttingen. Growing up in a home that valued knowledge greatly contributed to Max’s success in school from an early age.
Planck attended Maximilians Gymnasium in Munich, where his love for physics first began. He later studied at universities in Munich and Berlin, where he met influential physicists like Hermann von Helmholtz and Gustav Kirchhoff. In 1879, he earned his doctorate with a dissertation focused on the second law of thermodynamics. After that, he worked at multiple universities, beginning at the University of Kiel before moving to the University of Berlin. Initially, thermodynamics captured his attention, but he soon delved into black-body radiation, which led to a major discovery.
In 1900, Planck introduced the revolutionary concept of energy quanta. He proposed that energy is emitted and absorbed in specific amounts called “quanta,” a groundbreaking idea that emerged from his work on black-body radiation. This discovery was a game-changer, as it explained discrepancies between experimental results and classical physics theories. Planck’s constant (h), which became fundamental to quantum mechanics, is named in his honor. Due to his groundbreaking contributions to physics, he was awarded the Nobel Prize in 1918. His research laid the foundation for quantum mechanics and inspired future scientists like Albert Einstein, Niels Bohr, and Werner Heisenberg.
Life was not without hardships for Planck. His first wife, Marie Merck, passed away in 1909, and he tragically lost two sons—Erwin and Karl—during World War I. In 1911, he married Marga von Hoesslin, who supported him through these difficult times. Despite the political turmoil in Germany, Planck continued teaching and researching well into his later years. During the Nazi regime, he faced significant challenges due to his opposition to their policies and his support for Jewish colleagues. However, he never abandoned his dedication to science.
Max Planck passed away on October 4, 1947, in Göttingen, Germany. His legacy endures through the Max Planck Society for the Advancement of Science, a major research organization named in his honor. Planck’s work opened new frontiers in science and technology, and his ideas remain vital to modern physics, solidifying his place as one of history’s most significant scientific figures.
