The original name of the school was the “Wicker Park Achievement Skills Center.” It was changed on January 6, 1986 to “A. N. Pritzker School” in honor of the 90th birthday of
Abram Nicholas Pritzker, a 1913 graduate of the Wicker Park School. Two construction workers, employees of Coath & Goss Construction Co., found fossils of a giant beaver while digging footings during construction of the school. The bones were found about 6' below the surface either in the bottom of a 2-3' thick peat layer, or on the top of a blue clay layer underneath the peat. The bones represent the extinct beaver
Castoroides ohioensis. The specimen consists of a large upper incisor, and the palate of the skull with most of the "cheekteeth". The fossil is in the collections of the Field Museum of Natural History, catalogue number PM 3942. ==Parent–teacher organization ==
