John G. Hacker Catholic Hymnal reviews, 1920-1924

The Father John G. Hacker collection, 1920-1950, contains letters and biographical information about Father Hacker sent from Loyola College to R.L. Slingluff, incoming letters to Father Hacker from friends and Maryland government officials, reviews of his "Catholic Hymnal" book, and music he composed or used for religious services. The letters and biographical information were sent by Reverend Francis X. Talbot, S.J., President of Loyola College, to R.L. Slingluff to help him compose a necrology for Father Hacker in a Society of the History of Germans in Maryland publication. Father Hacker had been a member of the society before his death and Slingluff states it is customary to write a biographical sketch for members who recently passed away. The incoming letters to Father Hacker are from friends and government officials such as the Mayor of Baltimore and Governor of Maryland to confirm or decline attendance at his Golden Jubilee. There are also letters from a publishing company, William H. Sadlier Inc., discussing delays with printing additional copies of "Catholic Hymnal" in 1945. Some of the letters are marked "answered" by Father Hacker. The "Catholic Hymnal" reviews are handwritten or typed notes from fellow priests or copies of reviews from magazines. The music documents include songs composed by Father Hacker and those played during religious services as well as Canisius College music event programs and lists of instrument players.
