After 6 weeks in New Orleans, the group was led by Philippine to Missouri. Later on September 8, 1818, she opened the first Sacred Heart school outside of Europe, a very significant milestone as it was also the first free and Catholic school west of Mississippi. It was to be named St. Louis Archdiocese.
St. Louis Archdiocese.
Maintaining and running the school on a very low financial means proved to be difficult and due to these difficulties and the lack of students, the school relocated to Florissant, Missouri which began to attract more students. Mother Duchesne then opened the first novitiate in 1827 and founded programmes for boarders in the City House school in St. Louis, which was a free day school and orphanage.
In 1841, Philippine’s wish to serve among the native tribe finally become a reality; upon specific request she was able to venture out with three other Religious of the Sacred Heart to Sugar Creek, Kansas, to establish a school for Potawatomi girls.
When she was 72 she could no longer be much help witn physical work and was unable to learn the Potawatomi language. She adopted the name "Women who always prayers" as she spent most of her time in Prayer.
Philippine Duchesne returned back to her original foundation and spent the last decade of her life there dying, on November 18, 1852, at the age 83. She was beatified in 1940 and canonised in 1988 and her Feast Day is November 18.
2018 marks the bicentenary of not only Philippines death but her legacy. She was a pioneer and teacher who crossed new frontiers in order to provide education to children and inspire confidence within them despite the hardships she endured.
