‎First edition of Lebesgue's lectures on integration, held 1902-03 at Cours Peccot at the Colege de France, summing up his work on the Lebesgue Integral, which is now considered definitive.""Although Lebesgue was primarely concerned with his own theory of integration, he played a role in bringing about the development of the abstract theorie of measure andd integration that prdominate in contemporary mathematical research.""(Thomas Hawkins in DSB).‎
