Fr. Damien, born 1840 in Tremeloo, Belgium. He joined the Congregation of the Sacred Hearts volunteering for the mission to the Hawaiian Islands. In 1873 he went to work as a priest in a leper colony on the island of Molokai. He died from leprosy in 1889 aged 49. The testimony of the life he lived among the lepers of Molokai led to an intensive study of Hansens disease, eventually leading to a cure. Pope John Paul II beatified Damien in 1995. He was named a saint on Oct 11th 2009.
Fr. Damien was a member of the Congregation of the Sacred Hearts of Jesus and Mary. This video explains why the symbol of the Sacred Heart was such a strong motivation for him in living such a meaningful life.
