Hal Dunegan has been a household name in Acoustic Emissions since the 1960s
His original research at Lawrence Livermore Laboratory and subsequent technical publications led to wide-spread acceptance of acoustic emissions as a new tool for non-destructive testing of materials and structures. In fact, most companies currently involved in the field of acoustic emissions can trace their lineage back to this original work.
When the Acoustic Emissions Working Group (AEWG) was formed in 1967 by the world’s leading AE researchers and scientists, Hal was elected as the first chairman. Hal would go on to earn the groups recognition as the first winner of the AEWG “Achievement Award” and election as a “Charter Fellow” in 1982 followed by the groups “Gold Medal” award in 1984.
Along the way, Hal formed Dunegan Research Corporation in 1968 which was later acquired by Endevco in 1972 and operated as Dunegan Endevco where Hal served as president of the Dunegan Division until 1978. Whether running his own small business or a large multinational, Hal was always very “hands-on” with his customers and tirelessly travelled the world to introduce AE technology.
