Wright of Odenton, Maryland. Edward Wright (on left) received his B.A. with Honors in Mathematics from Rhodes College (formerly Southwestern at Memphis) in 1968, followed by his Ph.D. in Mathematics from the University of Notre Dame in 1973. Ed's thesis was on compact Kahler manifolds that admit Killing vector fields. After graduate school Dr. Wright was a visiting assistant professor at Notre Dame for one school year,then worked as an (applied) mathematician for the Department of Defense for 39 years. Ed retired 2014. Ed writes: "The only time I ever used a slide rule was in high school physics (1963/64). I started collecting them off of Ebay in the 2004/5 time period. I continue to marvel at how much was accomplished with these instruments. I am in the process of down sizing the modest collection that I have, and wanted them to go some place that will preserve this part of the technology."

He spent one year at the Rose Polytechnic Institute and in 1900 opened his Toledo office for private engineering practice. He married Harriet May Noble (1872-?) of Indianapolois, Indiana. His arrival in Toledo coincided with a boom in the development of interurban electric railroads and he became a specialist in that field. In those years he devoted much time in pavement design and construction. He was a part time instructor in the University of Toledo engineering college,, vice chairman of the Toledo City Plan commission, chairman of the Lucas county planning commmision, and assisted the city civil service commision in the examination of applicants for engineering positions. He advised the city in its water supply and sanitation engineering problems, and was active in the development of the Transcontinental airport and in harbor projects. At the time of his death, at age 69, he was on the way home from working on a rail project in Missouri. One of his more notable projects, still standing today, is the High Blue Boy Anthony Wayne Bridge which is a high level three-span steel suspension bridge in Toledo, crossing the Maumee River. and was completed in 1931. George Champe's name can be found on the plaque commerating the bridge engineers.
