She was born in Grenoble, France, August 29, 1769, the same year as Napoleon Bonaparte. Her father, Pierre François Duchesne, was a prosperous lawyer, practising in the Parliament, or law court of Grenoble, the capital of the Province of Dauphiny, while her mother, Rose Perrier, belonged to a family of wealthy merchants of the same city. Pierre François Duchesne had adopted the false teachings of Voltaire and his school, but his wife was very pious, and carefully brought up her children in the love and fear of God. Philippine was the next to the last in a family of six. From her earliest years she was noted for her serious turn of mind. One of her chief pleasures was reading, but even this had to be of a serious kind. Roman history was an especial favorite, but what she loved most of all was the lives of the saints, particularly the martyrs. Another of her pleasures was to assist the poor. All of her pocket money, with everything else that she could dispose of, went to them, and she loved to distribute her alms with her own hand.
At the age of twelve she was placed as a pupil at Sainte Marie d'en Haut, the Visitation Convent of her native city, to be prepared for her first Holy Communion. The remarkable spirit of prayer, of which she had given very early evidence, developed itself here, and her happiest moments were those she was permitted to spend in adoration before the Blessed Sacrament. A diligent and conscientious student, so ardent was her piety, that she was allowed by the kind nuns the privilege of making her morning meditation and reciting the Office in choir with them. The year after her admission into the school she made her First Communion, and it was on this happy occasion that she heard the call to a perfect life. Her parents, suspecting what was in her mind, removed her from the Convent. She silently acquiesced in this decision, keeping her own counsel, and continuing her studies with great success, in company with her cousins, the young Perfiers, who were afterward at the head of a great banking business in Paris, under the rule of the first Napoleon.
After four years of patient waiting, in the hope of obtaining her parents' consent, and convinced at last that they never would grant it, she decided that it was time to act, and entered the novitiate of the Visitation. Her family became somewhat reconciled to her choice, after striving in vain to induce her to return home; but when the time for her profession came, her father absolutely forbade her to make it, on account of the dangerous political conditions of the time.
Four years later, in 1792, when the revolutionary storm was at its height, religious communities were being everywhere expelled from their homes, and Monsieur Duchesne withdrew his daughter from her convent, which was soon converted into a prison, and went to reside with his family in the Chateau of Granne, situated in a retired part of the country. By this time all her sisters were married, except the youngest, a child in her 'teens; and when her mother was overtaken by her last illness, she it was who cared for her with devoted affection, and finally closed her eyes in death. After this the family possessions were divided among the children, and Philippine surrendered her share to the others, reserving only a small pension, barely sufficient for her needs.
This business being settled, she removed to a modest apartment in Grenoble, in order to be able to devote herself to works of mercy. Her ardent charity and intrepid energy found a wide field of action in those calamitous times. She visited and succored the unfortunate victims doomed to the guillotine, with whom the prisons were crowded. She ministered to the sick, and sought in their hiding places, the devoted priests who would not abandon their posts, to bring them to the bedside of the dying. She did all this at the constant risk of her life, often hearing sounds and witnessing sights that made her shudder with horror. As soon as the revolutionary storm had spent its fury somewhat, she was enabled to turn her attention to the neglected boys she found in the streets, assembling them in her own lodgings to teach them to read and write, and above all, to prepare them for the Sacraments.
At last, when the advent of Napoleon to power restored political and social order, Philippine Duchesne who, during all these years, had considered herself as irrevocably consecrated to the service of God, observing the rules and customs of the Visitation as closely as the adverse circumstances of the time would permit, resolved to reestablish in their old home the surviving members of the community of Sainte Marie d'en Haut, and resume a religious life with them. She obtained possession of the convent through the influence of her cousins, the Perriers, but her attempt to reorganize the community was not successful. In the meantime, however, several companions had gathered around her, forming a little community with the title of "Daughters of Faith," under the direction of the Vicar General of Grenoble, the Abbé Rivet. This was in 1803 and the following year.
In the meantime, Madame Duchesne had heard, through the Abbé Rivet, of the Society of the Sacred Heart recently founded by Mother Madeleine Sophie Barat, under the guidance of Father Joseph Varin. It was through the latter that she applied for admission into the new Society. Father Varin, in reporting the case to the holy Foundress, declared that Madame Duchesne was a soul worth seeking for even to the end of the world. Lack of space does not permit us to dwell upon the beautiful humility, submission and childlike docility this valiant woman displayed in her intercourse with her new superior, who was ten years younger than herself, or her joy at finding herself under religious discipline and obedience. Nor can we stop to describe her heroic devotedness, zeal and charity toward all; her incredible activity, her self-immolation, the wonderful spirit of prayer that held her motionless the livelong night before the Tabernacle, when holy obedience allowed her the privilege.
The ten years that followed her profession were spent at Sainte Marie d'en Haut, toiling with an unflagging energy vivified and made fruitful by her intimate union with God. It was during that interval that the death of her father occurred. In his last illness, she surrounded him with the most loving care, and had the consolation of bringing him back to the faith of his baptism, and seeing him atone for the errors of a lifetime by a sincere repentance and an edifying end.
In the depths of her heart, Mother Duchesne had felt from the first an intense longing to devote herself to the evangelization of the barbarous tribes still sitting in darkness and in the shadow of death; but hitherto she had not seen any opening in that direction. So she was patient and put out her hands to all the strong things that Divine Providence placed in her way. One day, however, the illustrious Dom Augustin de Lestrange, Abbot of La Trappe, visited Sainte Marie d'en Haut, on his return from a tour among the North American missions. It was on the feast of Pentecost, a circumstance that did not escape the piety of Madame Duchesne; and the account he gave of the labors, dangers and fatigues endured by the missionaries in the New World, communicated a new and almost uncontrollable intensity to her apostolic yearnings. After this, she was possessed by one thought and one desire, that of devoting herself to the conversion of the savages of America. A few days later, she wrote to Mother Barat to tell her of Dom de Lestrange's visit and of the ardent desires his discourses had aroused in her heart for the missions of America in particular. Mother Barat was delighted, but insisted that she must school herself to patience, until some providential opening should offer. For this she waited twelve long years, but with what burning desires, what tears and prayers! It would take too long to relate the circumstances which led to the visit of Mgr. Louis Valentin Dubourg, the newly consecrated Bishop of Louisiana, and describe the touching scene, when Mother Barat, in presence of the humble yet ardent entreaties of her strong-souled daughter, recognized the will of God, and gave the consent she implored, to let her have a share in the missionary labors of the zealous prelate in the far-off region of Louisiana.
In the hearts of God's saints, joy and sorrow are in close alliance. Mother Duchesne was overwhelmed with joy on seeing the realization of her ardent and long-cherished desires; but a midnight blackness settled upon her soul, when she found herself about to sail away from the shores of sunny France, leaving behind her all that her loving heart held so dear, and with the conviction that the parting was final, as far as this life was concerned. But her strong spirit did not flinch for an instant, and the world would never have known how keenly she felt the sacrifice, were it not for a few lines in one of her letters to Mother Barat. Her companions were Madame Octavie Berthold, a fervent convert, whose father had been secretary to Voltaire; Madame Eugénie Audé, a young lady whose grace and elegance had been admired at the court of Savoy, and two lay sisters of tried virtue. After a tedious voyage of ten weeks in a small sailing vessel, they reached New Orleans on the Feast of the Sacred Heart, May 29, 1818, and as soon as it was possible, they set out for St. Louis in one of the primitive steamboats of the time, a trip of six weeks, with numberless inconveniences and a very rough set of fellow-passengers.
