"''Riemann's conditions for integrability and their influence on the birth of the concept of measure''" (English translation of title) is an article on the history of measure theory, analyzing deeply and comprehensively every early contribution to the field, starting from Riemann's work and going to the works of Hermann Hankel, [[Gaston Darboux]], [[Giulio Ascoli]], [[Henry John Stephen Smith]], [[Ulisse Dini]], [[Vito Volterra]], [[Paul David Gustav du Bois-Reymond]] and [[Carl Gustav Axel Harnack]].
