Donald A. Bloch, MD: a remembrance.

When someone dies, the world, or at least a representative portion of it, should stop, take note, weep, give thanks, and then measure the influence of that life on those it has touched so that moving forward is made more meaningful. This article takes a moment to remember Donald A. Bloch, MD. Bloch was a visionary and an innovator who chose collaboration as his primary methodology for creating change. He introduced us to the "dual optic," in which "Dr. Biomedicine" and "Dr. Psychosocial" work hand in hand with the patient and family. In addition to being a visionary, Don was an "architect/urban planner", who helped build communities and coalitions that promoted new ideas and championed novel initiatives. He was one of the founders of Family Systems Medicine (now Families, Systems, and Health), which is the field's vanguard journal.
