Bruce A. McKenzie, an extension agricultural engineer at Purdue University, is an established national and international leader in the area of system planning for grain and feed handling facilities. He has been called upon to advise the governments of Brazil, Argentina and Venezuela on grain drying and storage problems. After earning B.S. and M.S. degrees in agricultural engineering at Purdue and Michigan State University, McKenzie was named assistant professor and agricultural engineer at Purdue, and was promoted to associate professor in 1963 and full professor in 1969. While working on grain drying and handling problems, McKenzie has become a prolific writer, speaker and workshop leader on all aspects of the technologies that comprise grain-feed handling systems. Over 50,000 copies of his extension leaflet, “Selecting a Grain Drying Method,” were distributed. He conceptualized and developed over 90 percent of the contents of a grain-feed handling system book, a 65-page manual still in use today. He played a key role in Cooperative Extension Service programming when the corn leaf blight devastated the 1970 corn crop, and in 1972 when the Gibberella mold attacked the corn crop. He organized over 60 educational meetings concerning alcohol production, problems and cost-benefit issues. McKenzie has also excelled as an undergraduate teacher of “Farmstead Machinery Management” for over ten years. He has served as chairman of two committees and a member of two other committees of the American Society of Agricultural Engineers, and as chairman of the Indiana Section of ASAE. He is a member of two standing committees of the National Council for Agricultural Science and Technology, and is one of three ASAE representatives to the council. McKenzie has received the Fredrick L Hovde Award of Excellence in Educational Service to Rural People of Indiana, the Purdue University Cooperative Extension Service Association Senior and Career Awarded the ASAE Metal Building Manufacturers’ Association Award, the U.A.D.A. Superior Service Award, and was elected a fellow of the ASAE.
