Harold E. “Bud” Nelson, known to many as “the most influential fire protection engineer of the 20th century” and the father of the emerging discipline, died on July 21 in Fairfax, Va., from complications after a fall, according to the Society of Fire Protection Engineers (SFPE). He was 82 and lived in Bethesda, Md.
Fire protection engineering is considered a unique subset of construction, but its high-profile industry status today may stem from the pioneering 60-year career of Nelson, who developed many innovations in fire protection design, modeling and systems ap-proaches that have improved building safety, particularly in high-rise structures.
