Before age 35, Holman hit over 0.500 at the University of California Los Angeles (UCLA); was recruited by professional baseball; led the Association of Interns and Medical Students and the International Union of Students in Denmark; had his passport confiscated; was stripped of a prestigious internship; shadowed by the Federal Bureau of Investigation ; grilled before a Senate committee on subversive activities; made a major medical discovery; and was recruited to be the new Chief of Medicine at Stanford. Holman was involved in building a leading academic institution. He expanded what medical students and graduates learned and what they researched. Holman saw the collision course between the technological capacity to do more and the growing expectations of the public. Moreover, he anticipated the monetization of health care and how it would widen the gap between what we know and what we practice in health care. He reinvented himself in population health. In contrast to reductionist laboratory-based research, his work embraced complexity and made action researchable and research action-oriented. Some innovations did not survive as originally conceived, but their ethos became mainstream. These included evidence-based management, shared physician-patient decision-making, self-management, critical evaluation of medical technology and diagnostics, and chronic disease management. Through the rise of the twentieth century American biomedical medicine, medical education, and slow-motion health care delivery crises that still occur, Holman changed the debate in a time when the funding, the people, the technology, and the need made all things seem possible.
