Marie-Thérèse Vauzou (August 10, 1825 – February 15, 1907)[1] was a French Catholic nun who is known as having been the Mistress of Novices and later Mother Superior of the Sisters of Charity of Nevers during Saint Bernadette Soubirous’ lifetime.

[2] Born Guillaumette Honorine in Collonges-la-Rouge, France; her father was Antoine Vauzou, a royal notary.

Some years before in 1858, Soubirous had become famous after having claimed to receive apparitions of the Immaculate Conception, now known as Our Lady of Lourdes.

As per her request, the canonisation process began in earnest two years later in 1909, with Bernadette officially declared a saint by Pope Pius XI in 1933.

[7] Sister Vauzou was portrayed by English actress Gladys Cooper in the 1943 film The Song of Bernadette, which was based on Franz Werfel’s 1941 novel of the same name.
