Hilda Katz Slosberg passed away the morning of November 27, 2017 at Rose Arbor Hospice Residence in Kalamazoo, MI, surrounded by children, grandchildren and great grandchildren. She was 90 years old, and the matriarch of the Slosberg, O'Brien, and Czocher families. Hilda graduated from University of Pennsylvania, 2nd in her class with a degree in social work.

Once the children were older, Hilda worked as the Director of Fishtown Library of Philadelphia, from 1974 until she retired in the early 1990s. She developed the Fishtown branch from a small community library, tentatively scheduled for closure, to a thriving community center. Hilda was fondly known at the library as the "Queen of Homework".
