Dr. Joseph Roland Troxler, a professor emeritus of mechanical engineering, died Nov. 4, 2010, in Scottsdale. He was 89.

Dr. Troxler was born Nov. 17, 1920, in Reserve, La. He was part of the original group of professors hired in 1968 to start an engineering college at what was to become Northern Arizona University. Alumni may remember that Dr. Troxler was deeply involved with the mechanical engineering students’ dune buggy races. He also was associate dean of Engineering and ran the co-op program matching students with employers around the state.

Dr. Troxler was a member of Living Christ Community Church who also enjoyed fishing and hunting.

Dr. Troxler is survived by his daughter, Wendy Bales (David) of Carrolton, Texas; sons Kirk (Lorinda) of Beaver, Pa., Wayne (Jane) of Brandenton, Fla., and Keith (Beth) of Scottsdale; sisters Theresa Blackledge (Dick) of Coronado, Calif.; 18 grandchildren; and eight great-grandchildren.

He was preceded in death by his wife, Aileen (Kit) Troxler.

Services will be scheduled at a later date. The family suggests memorial contributions be made to NAU Foundation, Joe and Kit Troxler Scholarship Fund.
