Known for her generosity and compassion, Marilyn Kroc Barg was the daughter of Ray Kroc, the man who turned McDonald’s into a multinational fast-food conglomerate. But Marilyn’s life was much more than her well-known familial ties. She left a lasting impression through her committed philanthropic work, particularly through her founding of Ronald McDonald House Charities, a charity that offers shelter and support to families with children who are critically sick.
