IN MEMORIAM
In 1979 he joined the Office of Surface Mining in the US Department of Interior, where he rose to Chief of the Division of Abandoned Mine Lands before transferring to the Bureau of Mines, where he managed the research programs of the Divisions of Mining Technology and Environmental Technology. When the Bureau of Mines became part of the Minerals Management Service in 1995 he became Senior International Programs Officer in charge of Latin America and the Caribbean, liaising with the State Department and the Executive Office of the President. After his retirement in 1996 Allen continued to advise on domestic and international min- eral and energy policies and on their technical ramifications.
Prof. Gabriel Filippelli writes that Allen was a long-time friend of, and Adjunct Faculty member at, University of Indiana-Purdue University Indianapolis (IUPUI): “He served as my informal external advisor, and our monthly lunches were filled with advice, stories of a remarkable career, and plenty of opportunities for me to bounce ideas off of him. I cherish memories of those lunches”. Allen was also a strong advocate for professional organizations and wrote a short paragraph that he gave to young colleagues encouraging them to become active in them. Allen was most proud of his long-term work assisting Native American tribes and developing world gov- ernments with the effective and environmentally responsible development of their mineral resources.
