Who is the author of the term "Coulomb logarithm"? In fact, Coulomb logarithm was computed by Langmuir in his paper of 1928 where the term "plasma" was introduced into physics, but the term "Coulomb logarithm" seemed to appear later. The earliest reference I found is the paper Relativistic kinetic equation by Belyaev & Budker (1956).

UPDATE: Using Google Labs I found a reference dated by 1937 in very rare Georgian journal in Russian.

Have you checked to make sure that Boltzmann or Maxwell did not have a hand in this? The term comes from impact parameter estimates and their work on gas theory might contain early versions of this. – honeste_vivere Apr 24 '15 at 12:25
