Benedictine Sister Margaret Ann (Mary Denis) Holtz, 92, died Nov. 30 in St. Joseph Court, the infirmary of St. Scholastica Monastery. She was a member of the Benedictine community for 74 years.

Born in Pennsylvania, Sister Margaret Ann visited her aunt Sister Gertrude Holtz, OSB, on a family trip to Chicago. She entered the Benedictine Sisters of Chicago in 1950.

For decades, Sister Margaret Ann taught primary grades at schools throughout the Archdiocese of Chicago, including Queen of All Saints, St. John Nepomucene, St. George and St. Hilary, where she also served as assistant principal. She also taught at Mother of God School, Waukegan; and in Colorado.

As was the practice in religious communities at the time, Sister Margaret Ann took college courses while teaching; in 1964, she earned a bachelor’s degree from DePaul University.

In the late 1970s, Sister Margaret Ann moved from teaching into positions of financial responsibility for both schools and community. She served in the business office of St. Scholastica Academy, Chicago, eventually becoming treasurer. Her ministry also included an appointment as treasurer of the Benedictine Sisters of Chicago. In her later years, Sister Margaret Ann coordinated monastery resources and housekeeping staff.
