Ray Henkel, 86, passed away March 11, 2017. He was drafted by the Army, and soon was commissioned an officer in the Corps of Engineers. He graduated from ASU in 1960 then went to the U. of Wisconsin for his M.A. and Ph.D. work with both degrees in geography (but with extensive work in agricultural economics).  His research was on tropical settlements and agriculture, particularly on cocaine production. He became the premier expert on the production, processing, transport and distribution of cocaine. He taught at ASU from 1966 to 1995, with leaves to teach two years in Zambia and one at New Mexico State. Ray is survived by three brothers.
