Graduate student in William Kouwenhoven's Johns Hopkins defibrillator
program, credited with the incidental observation that redirected the
team toward manual chest compression, and third-listed co-author on
Kouwenhoven, Jude & Knickerbocker's foundational 1960 *JAMA* paper. He
matters to the vault beyond the citation: his own 2012 first-person account
of the discovery (a JEMS interview) describes a materially different
physical circumstance than the vault's existing NIST-sourced retelling —
deliberate manual compression during an equipment delay, not incidental
paddle-weight pressure — an unresolved contradiction the vault now tracks
explicitly rather than silently reconciling.
