Holger Peter Sandhofe (7 January 197224 May 2005[1]) was a German typesetter and scholar of Gregorian chant.
Sandhofe studied music theory, medieval Latin, and history in Bonn. He mainly worked on producing musical editions for the older (pre-Vatican II) forms of the Roman Rite, and was involved in obtaining permission to hold services according to this form of the liturgy at the Alt-St.-Nikolaus church in Bonn. He also led a schola cantorum which sang the services according to the Germanic forms of chant in the manuscripts of Klosterneuburg.[2] In 2002 he produced an edition of the Nocturnale Romanum containing all the chants for the observance of Matins according to the Roman Breviary throughout the year.[3] Sandhofe drew on an "eclectic selection" of sources, writing some of the chants himself.[4]
Sandhofe died on 24 May 2005 at the age of 33 following a long illness.
