A timeline of events related to information theory, quantum information theory and statistical physics, data compression, error correcting codes and related subjects. * 1872 – Ludwig Boltzmann presents his H-theorem, and with it the formula Σpi log pi for the entropy of a single gas particle * 1878 – J. Willard Gibbs defines the Gibbs entropy: the probabilities in the entropy formula are now taken as probabilities of the state of the whole system * 1924 – Harry Nyquist discusses quantifying "intelligence" and the speed at which it can be transmitted by a communication system * 1927 – John von Neumann defines the von Neumann entropy, extending the Gibbs entropy to quantum mechanics * 1928 – Ralph Hartley introduces Hartley information as the logarithm of the number of possible
