Theodore Marier

Theodore Norbert Marier (October 17, 1912 – February 24, 2001) was a church musician, educator, arranger and scholar of Gregorian Chant. He founded the St. Paul's Choir School in Cambridge, Massachusetts in 1963, and served as the second president of the Church Music Association of America.

Marier once said he "got hooked on chant" as a college student in the 1930s when he heard a 78 rpm recording of the choir of the Abbey of Solesmes, France. "It was the most beautiful music I had ever heard", he said. He later studied at Solesmes under Dom Joseph Gajard.

A graduate of Boston College, he was director of band and music there from 1934 to 1942. In 1940 he received a master's degree from Harvard, and over the course of the years he was also choir director or lecturer at Emmanuel College, Newton College of the Sacred Heart, and Boston University.

In 1934, Marier began fifty-two years of musical service at The Church of St. Paul (Harvard Square) in Cambridge, Massachusetts, first as organist and from 1947 as choir director. In 1963, with Monsignor Augustine F. Hickey, he founded a choir school associated with the parish, St. Paul's Choir School, and directed it until his retirement in 1986. The school later became known as the Boston Archdiocesan Choir School, and the choir, the Boston Boy Choir, though as of April 2014, the school's original name has been reestablished.

In the 1950s, Marier was a faculty member of the Pius X School of Liturgical Music at Manhattanville College. In that capacity, he contributed to editing The Pius X Hymnal (1953).

In 1966 he was elected president of the Church Music Association of America, succeeding Rembert Weakland.
