Henri Marie Camille Édouard Alby (5 November 1858[1] – 11 February 1935) was a French army general who served during the First World War.

There, he served for a year before being promoted to lieutenant, and participated to the French conquest of Algeria during the pacification of the territories south of Oran.

Alby finally became Chief of the Army Staff in December 1918,[3][4] a month after the armistice, replacing Marshal Foch who remained Supreme Allied Commander until 1920.

[5] His future successor to the position, General Edmond Buat,[6] wrote in his personal journal his dismay over Alby's appointment at the time: A brave but very poor man.

Neither a leader, nor even a soldier, one can already find it astonishing that, dismissed from an army corps, he was chosen for the rear general staff, then - insanity!
