Theodore Marier

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.

He was also a member of the board of directors of the Institut für Hymnologische und Musikethnologische Studien, Maria Laach, Germany; and a fellow of the American Guild of Organists.

[7] Cardinal Bernard Francis Law celebrated Marier's funeral Mass at The Church of St. Paul (Harvard Square) in Cambridge.

"Professor Marier effectively transmitted his inspiration about Gregorian chant to generations of Catholic musicians", wrote Helen Hull Hitchcock, editor of the Adoremus Bulletin.

She had been recruited to sing in a schola Marier conducted at a symposium of the Church Music Association of America where she had given a lecture on liturgical translation.
