Daniel Harris, associate principal of Ida Crown Jewish Academy in Chicago, has turned his love of baseball into a lesson about values by collecting baseballs signed not by Hall of Famers, but by leading Rabbanim and Gedolim.

What started as sports memorabilia became a way for him to show students who his true heroes are and to spark conversations about greatness, character, and Torah.

And over the weekend, he added to that one-of-a-kind collection again, this time by having HaRav Moshe Hillel Hirsch sign a baseball while visiting Chicago.
