Władysław Natanson (1864–1937) was a Polish physicist.
He was head of Theoretical Physics at Jagiellonian University from 1899–1935.[1][2] He published a series of papers on the problems of thermodynamically irreversible processes, gaining him recognition in the rapidly-growing field. He was the first to take into accout the distinguishability of photons in the statistical analysis of elementary processes, being a precursor of the notion of quantum indistinguishability[3][4].
