In Memoriam: July 2018

IEEE mourns the loss of the following members

23 July 2018

Denis William Aull

Telcomm engineer

Member, 62; died 4 June

Born in Indianapolis, Aull was the valedictorian of his class at the Latin School of Indianapolis, a Catholic preseminary high school for boys. He went on to earn degrees in electrical engineering at Purdue University, in West Lafayette, Ind., and at Caltech. After graduation, he worked as a research engineer at Bell Labs.

In 1982 IEEE recognized his work on telecommunication circuit technology with a Best Paper Award.

He rose to high-level management positions, directing research divisions and business units at a number of companies including Avaya, Intel, and Lucent. He was known as a manager who could turn around a failing department, both because of his technical know-how and his ability to lead teams and lift morale.

 Aull was concerned about society’s underserved people, and he supported a number of progressive causes. Each June he raised money for Planned Parenthood. He was a staunch supporter of public broadcasting as well as environmental causes.

In his final years, he lived with his wife, Linda, in Florida, and they traveled often to the Caribbean.

John Bradford Eads

Design engineer

Life senior member, 73; died 12 January

Born in Charleston, N.C., Eads grew up with a passion for music. He designed and built a 12-string guitar, a computer, and a color television before he got to college.

He was an original member of the Kanawha Rocket Society, where he designed, built, and tested rockets with his team at Kanawha State Forest, near Charleston, W.Va.

He went on to study electrical engineering and geology at Virginia Tech. While there, he was an active member of the spelunking club. He raced for the Yamaha Enduro motocross team and hosted a late-night radio show on the school radio station.

Eads worked for the U.S. Army Corps of Engineers in Huntington, W.Va. After that, he was a design manager at Poly Scientific Corp., in Bay Shore, N.Y., and Electro-Tec, in Blacksburg, Va., helping to design a component of the self-propelled Chaparral missile.

He moved to Sarasota, Fla., and became a bonsai specialist at a nursery. He then became a greens manager at the town’s golf course before retiring.

During retirement, he started a YouTube channel where he shared his love for cooking, as well as an online forum to help others with technical problems.

Donald J. Ewing

Computer scientist

Life senior member, 87; died 9 March

After graduating from the University of Toledo, Ohio, Ewing became a teaching assistant at MIT and went on to become an electrical engineering instructor. He then returned to Toledo, where he was named the first chair of the university’s computer science and engineering program.

In 1973 he relocated to Dhahran, Saudi Arabia, and became chair of systems engineering at King Fahd University of Petroleum and Minerals. He went back to the University of Toledo in 1980, then set up a data communications network at the Lewis Research Center in Cleveland with a grant from NASA.

After he retired, he became professor emeritus at Toledo and served as interim chair of the computer science and engineering program. He then became a member of the College of Engineering’s visiting advisory board. He ran a computer consulting business at the same time.

Ewing was a member of the IEEE Computer Society.

He received a bachelor's degree in electrical engineering from Toledo and a doctoral degree from the University of Wisconsin, Madison.

Raymond P. Jefferis

Professor of electrical engineering

Life member, 79; died 25 March

Jefferis was a professor of electrical engineering at Widener University, in Chester, Pa. for more than half a century.

For 25 years, he founded and ran Hieronetics, which designed and manufactured testing and calibration equipment for the pharmaceutical and coal refining industries. He held two patents: one on a way to use chlorine gas to sterilize medical instruments and another for removing impurities from coal particles during the refining process. He spent two years as a Fulbright scholar at the Institute of Microbiology at Technische Universität Braunschweig, in Germany.

Jefferis was a member of the IEEE Computer Society.

He volunteered at the Chester County Department of Emergency Services, helping with phone outages and other issues by providing backup-communications support. He also volunteered and did work in communications for the American Red Cross.

He earned a bachelor’s, master's, and doctoral degrees in electrical engineering from the University of Pennsylvania, in Philadelphia.

John Denis Enderle


Fellow, 65; died 2 April

Enderle was a professor at North Dakota State University, in Fargo, and the University of Connecticut, Storrs.

A teaching Fellow at both North Dakota State and Uconn, he spent most of his career studying human eye movement and traumatic brain injuries. He also was an evaluator for ABET (the Accreditation Board for Engineering and Technology) for bioengineering programs and a member of its Engineering Accreditation Commission.

He was the editor of the U.S. National Science Foundation book series on the foundation’s engineering senior design projects to aid people with disabilities, and he edited a biomedical engineering book series for Morgan and Claypool Publishers. He wrote three editions of a seminal undergraduate textbook for biomedical engineering.

Enderle was a member of the IEEE Engineering in Medicine and Biology Society.

He received bachelor’s, master’s, and doctoral degrees in biomedical engineering, plus a master’s degree in electrical engineering, from Rensselaer Polytechnic Institute, in Troy, N.Y.

IEEE membership offers a wide range of benefits and opportunities for those who share a common interest in technology. If you are not already a member, consider joining IEEE and becoming part of a worldwide network of more than 400,000 students and professionals.
