HABERL, FRANZ XAVER (1840-191o), German musi cian and writer on music, was born at Ober Ellenbach, Bavaria, on Apr. 12, 1840. He was educated and ordained at Passau, and in 1862 was appointed Kapellmeister of the cathedral and musical director of the two seminaries. From 1867-1871 he was in Rome. He then settled at Regensburg, where he established the school of ecclesiastical music. In 1879 he became honorary canon of the cathedral of Palestrina and founded the Palestrina Soci ety. He died at Regensburg on Sept. 5, 191o, having been domes tic prelate to the Pope since 1907. Haberl's research in 16th century music is of cardinal importance. In connection with the Palestrina Society he completed the editing of Palestrina's works in thirty-two volumes, recovering many of the lost compositions and bringing out the whole work in time to celebrate the ter centenary of the composer's death in 1894. He then began to prepare a similar edition of Lassus. His contributions to the Bausteine zur Musikgeschichte, the Cdcilien-Kalendar (later, Kirchenmusikalisches Jahrbuch), and the Monatshe f to fur Musik geschichte are invaluable to students of musical history. Of special importance is his thematic catalogue of the Sistine Choir archives in Eitner's Monatshe f to (1888) . He was also a member of the commission for the publication of the Denkmiiler Deutscher Tonkunst. Among his publications are the Lieder-Rosenkranz (1866), a selection of Frescobaldi's organ works (1889), and the Magister choralis (1865), which has run through many editions and exists in six languages.
