Death of Max Planck (German physicist, quantum theory founder), October 4. Max Planck was a pivotal figure in the history of theoretical physics, known for introducing quantum theory and fundamentally transforming humanity’s understanding of matter and energy. Born in Germany in 1858, Planck devoted much of his life to research and teaching at German universities. His quantum theory, presented in 1900, laid the foundation for a new branch of physics and paved the way for the work of scientists such as Albert Einstein and Niels Bohr. Throughout his scientific career, Planck received numerous awards and honors, including the Nobel Prize in Physics in 1918. His contributions had a profound impact on the development of modern technologies, including electronics and communications. During World War II, Planck faced significant challenges but continued his scientific and educational activities. On October 4, 1947, Max Planck died at the age of 89 in Göttingen, Germany. His legacy as the founder of quantum theory and a pioneer of modern physics is recognized in scientific and cultural calendars worldwide. This date was added to the Gregorian calendar to commemorate the historical and scientific importance of Max Planck’s achievements and their enduring influence on fundamental sciences.
