Franz Viktor Werfel was an Austrian-Bohemian novelist, playwright, and poet whose career spanned World War I, the Interwar period, and World War II. He is primarily known as the author of The Forty Days of Musa Dagh, a novel based on events that took place during the Armenian genocide of 1915, and The Song of Bernadette (1941), a novel about the life and visions of the French Catholic saint Bernadette Soubirous, which was made into a Hollywood film of the same name.

Bernadette Soubirous, also known as Bernadette of Lourdes, was the firstborn daughter of a miller from Lourdes, in the department of Hautes-Pyrénées in France, and is best known for experiencing apparitions of a "young lady" who asked for a chapel to be built at the nearby cave-grotto. These apparitions occurred between 11 February and 16 July 1858, and the woman who appeared to her identified herself as the "Immaculate Conception".
