Katalin Karikó has had an unlikely journey. The daughter of a butcher in postwar communist Hungary, Karikó grew up in an adobe home that lacked running water, and her family grew their own vegetables. She saw the wonders of nature all around her and was determined to become a scientist. That determination eventually brought her to the United States, where she arrived as a postdoctoral fellow in 1985 with $1,200 sewn into her toddler’s teddy bear and a dream to remake medicine.
