    Lode (Louis H.) Huybrechts was born in Stabroek (Antwerp) Belgium on August 8, 1911. His musical training and early positions as an organist were in the same area. He emigrated to the United States and was an organist at Sacred Heart Cathedral in Rochester, New York. He served the Church of the Sacred Heart in Pittsburgh, PA as organist and choirmaster from 1960-1971. He died in Pittsburgh on January 3, 1973.





The Carnegie Library of Pittsburgh Music Department has been the recipient of a donation of many of Louis Huybrechts musical manuscripts and published works. This finding list for his scores in our collection is divided into two parts:

  1. Alphabetical listing of individual titles along with their arrangement (choral, organ, piano, etc.)
  2. Listing of items bound in folders, notebooks, and journals along with their arrangement.

The majority of the scores in this donation are manuscript copies. In the event of a published version included in addition to the manuscript copy, the entry is marked "published edition also." If only a published edition is included, the entry is marked "published edition only."
