The Architect of Trust: Dr Tom Ferguson's Legacy.

This article serves as a formal tribute to the legacy of Dr Tom Ferguson and his foundational 2007 white paper on the "e-patient." Despite its widespread influence, Dr Ferguson's original vision has often been internalized by the broader medical community without clear historical attribution, leading to a drift in the term's original meaning. This article restores the intellectual genealogy of the "e-patient" as defined by Dr Ferguson as "equipped, enabled, empowered, and engaged." We argue for the continued relevance of his "quiet giant" leadership. By formalizing Dr Ferguson's foundational white paper e-Patients: How They Can Help Us Heal Healthcare within this article, we ensure its preservation for future research and provide a stable foundation for the evolving field of participatory medicine.
