He was active in the Belgian resistance, and was one of three founders of an underground journal first published in 1918, Le Flambeau.

Mühlstein joined the Polish diplomatic service in 1919, assigned to Brussels. During that time, he was a member of the Polish delegation to the Locarno Conference and League of Nations assemblies. He was promoted and transferred to Paris in 1930.

In 1932, Mühlstein married Diane de Rothschild, daughter of French banker Robert de Rothschild. The couple had three daughters: Cécile, Anka, and Nathalie.

After the German invasion of France, Mühlstein moved to the United States. He returned to France after World War II.
