Josef Stefan was an Austrian physicist and mathematician, best known for his contributions to thermodynamics and statistical mechanics. Born on March 24, 1835, and passing away on January 7, 1893, he is particularly famous for the Stefan-Boltzmann Law, which describes how the total energy radiated per unit surface area of a black body is proportional to the fourth power of its absolute temperature. This law is fundamental in the study of thermal radiation.
