Judith Faulkner

Electronic health records. Faulkner founded the company that became Epic Systems in a Madison basement in 1979, writing patient-record software, and built it into the dominant supplier of electronic records to large American hospitals, run from a campus in Verona, Wisconsin. Epic stayed private, made no acquisitions and grew by in-house development. Hospitals praise its depth but criticise its cost, and it has faced long arguments over sharing data with rival systems.
