No one had very high career aspirations for teenager David A. Weston—except for Weston himself. Growing up in London, he scored low on the U.K. national assessment test given to students finishing primary school. The result meant that his next path was either to become a laborer or attend a vocational school to learn a trade.
What Weston really wanted to do was to work as a radio and TV repairman. He was fascinated by how the devices worked. He had taught himself to build an AM radio when he was 15. Even after showing it to his parents and teachers, though, they still didn’t think he was smart enough to pursue his chosen career, he says.

So, later that year, the underweight teen got a job on a construction site carrying heavy loads of building materials in a hod, a three-sided wooden trough. The experience convinced him he wasn’t cut out for manual labor. He eventually earned a certificate in radio and television, the only credential he holds. The lack of academic degrees did not hold him back, though. He went on to become an expert in electromagnetic interference (EMI) and electromagnetic compatibility (EMC). An EMI field has unwanted energy that causes interference. EMC is the capacity for electronic devices to work correctly in a shared electromagnetic environment without causing interference or suffering from it in nearby devices or signals. After working for a number of companies, he launched his own business more than 40 years ago: EMC Consulting, in Arnprior, Ont., Canada. The company has helped clients meet EMI and EMC regulatory requirements. Now 83 years old and retired, the IEEE life member recently self-published his memoir, From a Hod to an Odd EM Wave. “My memoir is about engineering persistence and human and technical discoveries,” he says. “I wanted to interest a young person, or perhaps a person later in life, in a career in engineering. If I can show that engineering is a personal, human endeavor with exciting opportunities in different fields such as medical, scientific, and the arts, maybe more women would be attracted to it.” From repairing radios to designing underwater devices In 1960 Weston enrolled in the radio and electronics program at London’s Croydon Technical College (now Croydon College). The school covered topics from the City and Guilds of London Institute’s radio and television certificate program. He attended classes one day a week for five years while working to put himself through school. Although his parents and his teachers might not have recognized Weston’s potential, employers did. He got his first job in 1960, fixing televisions in a small repair shop. Then he helped repair tape recorders. In his spare time, he studied transistors and semiconductors. Everything he knows, he says, he learned by reading books and research papers, and from on-the-job training. Later in 1960, he worked as a mechanical examiner for the U.K. Ministry of Aviation, where he calibrated precision meters and potentiometers, which are variable resistors that monitor, control, and measure industrial equipment.
“Engineering is creative. To have a new idea or design accepted is rewarding, satisfying, pleasurable, and even exciting.”
Weston’s Advice for Budding Engineers Follow the field in which you are most interested.
Don’t be afraid to work in other countries; it can be a rewarding, enriching experience.
Question the results of measurements or analyses. If it doesn’t seem right, it probably isn’t. Look at a similar publication on the same topic for a good correlation.
Don’t be too shy to ask simple questions. That’s how we learn and grow.
Keep an open mind.
The lab hired him in 1978, and the family moved to Long Island. After a few weeks of meeting with different departments, his boss asked him what kind of work he wanted to do. Weston told him about his idea for designing a device to detect a helium leak, should there ever be one. His machine would cover the entire 3,834-meter circumference area of the ring.
“The danger with increased helium-enriched air is that the oxygen level reduces until the person breathing becomes adversely affected,” he wrote in his memoir. “I found that the speed of the sound of helium increased enough to be detected, but not sufficient enough to cause a person trouble if they were in the tunnel.
“Brookhaven was considering machines that only covered a small area of the ring, but these would be unrealistic because too many machines would be needed, and the cost would have been astronomical.”
Weston’s system included an ultrasonic transmitter, a receiver, a power amplifier, and a preamplifier. It would sound an alarm if the helium content went above a certain level. People in the tunnel would be directed to go to the nearest oxygen-breathing equipment, put on a mask, and immediately evacuate. It was successfully tested.
Weston wrote a report detailing the ultrasonic helium leak detector, but shortly after, he and his wife had to return to Canada in 1978 because they were unable to get additional work permits in the United States.
When he returned to Brookhaven for a visit, his former boss told him the report was well-received. And he shared some news that upset Weston.
“My boss told me he took my report, changed the name on the report to his, did not mention me, and published the report as his,” Weston wrote in his memoir.
But the system was never built. The Isabelle project was canceled in July 1983 due to technical problems with fabricating the superconducting magnets.
Weston got a job working for CAL Corp., an aerospace telecommunications company in Montreal. For the next 14 years, he fixed EMI problems for the company’s products, including its charge-coupled device-based space-qualified cameras, which were designed to be carried aboard a satellite.
In 1992 he realized that nearly all his work involved consulting for the company’s customers, so he decided to start his own agency. CAL generously let him take the clients he worked with, he says.
Weston then conducted EMI analysis and testing and designed EMC systems for companies around the world.
“I always had enough customers and have never had to look for work,” he says. “For me, having my own business was more secure than working for a company.”
He retired in 2022.
IEEE as an educator
To broaden his education, he joined IEEE in 1976 to get access to its research papers and attend its conferences, he says. He is a member of the IEEE Electromagnetic Compatibility Society.
Because he is self-educated, he was “keen to learn as much as possible by reading practical papers published by IEEE,” he says. “I met people at IEEE symposiums and listened to the authors presenting their papers.”
Those included EMC experts such as Life Fellows Lothar O. “Bud” Hoeft, Richard J. Mohr, and Clayton R. Paul, whose papers are published in the IEEE Xplore Digital Library. Several of Weston’s papers are in the library as well.
His book Electromagnetic Compatibility: Methods, Analysis, Circuits, and Measurement references many IEEE papers on data and analysis methods.
“Engineering is creative,” he says. “To have a new idea or design accepted is rewarding, satisfying, pleasurable, and even exciting.”
