Francis Gally, real name Francis Jean Mazières, (28 October 1863 – 20 November 1918) was an early 20th-century French actor and playwright.
Francis Gally began a career in acting.
At the beginning of World War I, midinettes nicknamed Mimi Pinson, were making tricolor rosettes for the benefit of solidarity funds (a work led by Gustave Charpentier).
Henri Goublier thought that the current events could be a good subject operetta.
Goublier obtained the agreement of Maurice Ordonneau, one of the fashionable authors of the time for the libretto, a project which Francis Gally joined.
