Édouard Réquin

Then in 1916-1918 a member of the General Staff of Marshals Joseph Joffre and Ferdinand Foch.

It is at this time that a portrait of Réquin in military uniform was made by Kees van Dongen in 1916.

American military officials were impressed by Réquin's depiction of the situation in the French Army where whites and blacks served side by side and were cared for in the same hospitals and by the same personnel; they had his report La Course de l'Amérique à la Victoire published in English as America's race to victory (1919).

From 1930 he was French Military Representative at the League of Nations, and 1930-1932 Chief of Cabinet of Ministry of War.
