John Senders (1920-2019) / Peter A. Hancock, Gabriella M. Hancock, W. Senders, Abigail J. Sellen

We here survey and applaud the life and contributions of John W. Senders. Encompassing almost a century of experience, Senders's interests embraced vast swathes of knowledge, and he was at home in all ofthem. Most concerned with the application ofsolid experimental methods in pursuit ofsolutions to highly practical, real-world problems. Senders conceived ofand created many ofthe approaches we today consider standard. His work on scanmng still resonates in our modern world through the promulgation ofnational and international standards. His principled work on the practicalities of human error are considered crucial, especially because the area had been largely collections of ad hoc observations before his formalizations. His latter works in support of medical safety and the mitigation of transportation accidents continue to save the lives ofunaware thousands. In such shadows do true heroes lie.
