Distinguished Bruce D. Hammock (1947-2026) was a prolific scientist, gifted teacher, and extraordinary collaborator whose work transformed entomology, immunochemistry, and inflammation biology. Author of more than 1,500 peer-reviewed publications and collaborator with over 3,500 scientists worldwide, he combined scientific rigor with rare generosity and vision. His pioneering studies on juvenile hormone biology, immunochemical biomarkers of environmental exposure, and especially soluble epoxide hydrolase (sEH) reshaped understanding of inflammation and led to promising clinical therapies. A gifted communicator and mentor, Bruce, inspired generations of students and colleagues through his intellect, humility, and boundless enthusiasm. During the 28,635 days of his life, science and the world were richer for his presence.
