Marie-Jean-Lucien Lacaze

Marie-Jean-Lucien Lacaze (22 June 1860, Pierrefonds, Oise – 23 March 1955, Paris) was a French admiral, minister of Marine, préfet maritime and académicien.

He then took command of the Masséna, before serving as chief of cabinet to minister of the Navy Théophile Delcassé.

During the First World War, Lacaze led a division of the Mediterranean fleet, and organised part of the Dardanelles Campaign.

He was briefly acting War Minister in December 1916, between the resignation of Pierre Roques and the arrival of Hubert Lyautey from Morocco to take up the post.

Whilst in post he oversaw the removal of Ferdinand Foch from command of Army Group North and the replacement of Joseph Joffre by Robert Nivelle as Commander-in-Chief of the French Army on the Western Front.
