Louis LaRavoire Morrow, S.D.B. (24 December 1892 â 31 August 1987) was an American-born Roman Catholic bishop, Salesian of Don Bosco, missionary, and author. He served as Bishop of Krishnangar (West Bengal, India) from 1939 to 1969; founded the Sisters of Mary Immaculate congregation; and wrote several catechetical works that were widely used in Catholic schools.
Morrow was born on 24 December 1892 in Weatherford, Texas. His family later moved to Mexico, where he completed his education. He joined the Salesians of Don Bosco and was ordained a priest on 21 May 1921.
On 29 October 1939 Morrow was consecrated bishop and took charge of the Diocese of Krishnangar. He spent thirty years leading the diocese, focusing on building schools, churches, and charitable institutions. In 1948 he founded the Sisters of Mary Immaculate (SMI), a congregation dedicated to education, health care, and social work. The novitiate opened in 1950, and the first professions were made in 1952. In 1965 he inaugurated the new motherhouse and chapel of the congregation in Krishnangar.
Morrow encouraged education and helped establish several schools and parishes in the diocese.
He also promoted the building and renovation of parish churches, including the cathedral in Krishnangar.
Morrow resigned as Bishop of Krishnangar in 1969 and retired from active ministry. He continued to revise his catechetical writings and remained close to the SMI community. He died on 31 August 1987.
Morrow is best remembered for his catechetical books, many of which were used in schools and parishes for decades.
