ghmus7 is referring to Brother Howard Hughes, S.M., a member of the Marianists. Some of his compositions for the Office were printed (melody only) in the one-volume "Christian Prayer" edition of the LOTH, published by Catholic Book Publishing Co. A list of his works is at the U. Dayton website at: https://udayton.edu/imri/mary/m/music-by-howard-hughes.php
Looking through materials that I happen to have here, I found a few of his psalm tones included in these books: ICEL Resource Collection (GIA) Lectionary Psalms and Gospel Acclamations, Year B (WLP).
