s -particle distribution functions were introduced in classical statistical mechanics by J. Yvon in 1935. The BBGKY hierarchy of equations for s -particle distribution functions was written out and applied to the derivation of kinetic equations by Bogoliubov in the article received in July 1945 and published in 1946 in Russian and in English. The kinetic transport theory was considered by Kirkwood in the article received in October 1945 and published in March 1946, and in the subsequent articles. The first article by Born and Green considered a general kinetic theory of liquids and was received in February 1946 and published on 31 December 1946.
