I would like to offer my condolences to Dr. Hagenbach's family on his passing as well as inform them of the tremendous influence he had on my professional life. I worked for Dr. Hagenbach as an environmental engineer in Staley's Environmental Sciences group from 1981 until he retired. I have been with this group ever since an am currently its manager. I often ask myself if Bill would still be proud of the group he started and try to manage the group according to many of the principles he taught me. I believe the group has retained the respect it had for its technical abilities when Dr. Hagenbach was at the helm and am so appreciative of his legacy. He will be missed but never forgotten.
