During AIHA’s 75th anniversary celebration last year, The Synergist invited AIHA volunteers to submit responses to the question, “What ignited your passion for industrial hygiene?” The responses are collected on the AIHA website. Reading them now, as my term as AIHA president nears completion, I am reminded again of the hallmarks of our profession—dedication to the greater good, technical expertise, sound science—and of the deeply personal conviction that led many of us to become industrial hygienists. I am especially grateful to Dr. Ken Blehm, CIH, Professor and Associate Dean at Colorado State University, who ignited my passion for industrial hygiene. That conviction forms the root of much of what AIHA has accomplished over three-quarters of a century. This organization was founded by volunteers who believed that a professional home for industrial hygienists was necessary for practitioners to develop their technical skills, share best practices, and, ultimately, protect worker health. It is immensely satisfying to reflect that AIHA has remained true to these core principles throughout its long history while fostering productive collaborations across so many professional communities. Today, our reach encompasses entire industries and has grown beyond our traditional borders, as illustrated by our evolving relationship with our colleagues in China and India. GIVING BACK In 1999, the late Dr. Roy M. Buchan, CIH, Professor Emeritus, CSU, and Mary Lynn, CIH, CSP, OSHA, inspired me to run for a leadership position for the AIHA-Rocky Mountain Section. Since 2002, the source of my passion for industrial hygiene has been the good work that our volunteers do on behalf of the profession. That year, as the incoming local section president, I attended AIHA’s Leadership Workshop. The volunteers who shared their expertise made a deep impression on me, and the example they set by giving back to their professional community has guided me ever since.
