Louis Savinien Dupuis

Louis Savinien Dupuis was a nineteenth-century French Catholic missionary priest of the Paris Foreign Missions Society (Société des Missions Étrangères de Paris, MEP). He was born in 1806 at Sens, in the Yonne department of north-central France. After ecclesiastical studies he entered the MEP seminary in Paris, was ordained a priest in the early 1830s, and was assigned to the Pondicherry mission in South India, a field long entrusted to the Paris Foreign Missions. He reached India in that same period and remained in the Carnatic and Pondicherry region for the rest of his life. The mission then comprised the French colonial enclave of Pondichéry together with adjoining districts of the Tamil country. Dupuis never became a bishop; he served throughout as a missionary priest of the society.

In Pondicherry he combined ordinary pastoral work with education, seminary formation, and the mission press. The Pondicherry imprint produced catechisms, schoolbooks, and liturgical texts in Tamil for the local church and for fellow missionaries. Dupuis became one of the more notable Tamil scholars among the MEP clergy of his generation. He worked on Tamil grammar and on lexicographical tools, including Tamil–French and related dictionaries intended both to train European missionaries in the vernacular and to strengthen Tamil Christian literature. Such linguistic and printing labor was characteristic of the more scholarly members of the Pondicherry mission in the middle decades of the nineteenth century.

Dupuis is also remembered for his part in founding indigenous female religious life in that church. In the mid-nineteenth century he established, or took a leading role in establishing, a congregation of Indian sisters under the title of the Immaculate Conception, so that Tamil women could live a consecrated life and serve in education and works of charity among the local Catholic population. The foundation belonged to a wider pattern in nineteenth-century India, in which European missionaries, often with the support of the vicar apostolic, created native sisterhoods rather than relying only on European congregations. The Sisters of the Immaculate Conception of Pondicherry continued after his death as an institute serving schools and social works in South India.

He died at Pondicherry in 1874 after more than four decades in India. He was not beatified or canonized and has no feast in the universal calendar. His memory is preserved chiefly in the personnel records and necrologies of the Paris Foreign Missions, in the history of the Catholic Church in Puducherry, in the Tamil printed books associated with the mission press, and in the congregation of sisters he helped to found. A precise burial site is not recorded in the general biographical sources commonly available for MEP missionaries of that period.
