He was born in France and was attracted to the Oblates by an uncle who was already a missionary in Ceylon. At the end of his novitiate he was sent to the International Scholasticate in Rome, where he studied at the Gregorian University. He taught dogma in San Antonio, and after some time in parish work he became the provincial of the Second Province of the United States. The General Chapter of 1932 chose him to succeed Bishop Augustin Dontenwill as Superior General. Under his leadership the Congregation continued to expand its fields of apostolate: Laos, Philippines, Haiti, Brazil, Labrador, Cameroon, Congo, British Columbia, Yukon….

The last years of his administration were deeply troubled by the events of the World War of 1939-1945. In l943, Father Labouré, who was in need of complete rest, returned to France and left the general administration in the care of Father Hilaire Balmes, whom he appointed vicar general. He died in Paris on February 28, 1944.
