Biographer and historian of the American frontier, Louise Callan, RSCJ, in 1935:
"And through the whole of this, like a golden thread binding it into unity, runs the character of our greatest Indian missionary nun, Mother Lucile Mathevon - a novice of Mother Duchesne, foundress of the house of St. Charles (1828), and for about 35 years the very heart and soul of the Indian Mission.
She is just glorious - a Dauphinoise, but so different from Mother Duchesne - yet a SAINT. You see where my heart lies. I should thrill to write it all myself....You can imagine how little of all this I could include in one chapter of my dissertation, not 50 typed pages."
-Louise Callan, RSCJ, author of The Society of the Sacred Heart in North America (1937) and Philippine Duchesne, Frontier Missionary of the Sacred Heart (1957)
