TENGAM - Key Persons


Andrew Hirzel

Job Titles:
  • Senior Engineer
Andy is deeply involved in magnet FEA design, testing, manufacturing processing, quality control, and magnetization. Applications he has successfully undertaken have ranged from single-particle magnetization analysis to 500 kW 1000 Hz synchronous motors. His theoretical understanding (Maxwell's equations, anyone?) combined with practical factory experience provide a great fit to Tengam's team. You will find that every subject related to magnetics is interesting to Andy, no matter the detail. Andy graduated from the University of Michigan with a bachelor's in Industrial & Operational Engineering: a background that, like most magnet people, was not specifically in the field. He has wide-ranging experience in manufacturing, but after he drifted over to the domain of magnetics he has never quite broken free of that fundamental attractive force. When not looking for magnet flux, Andy stays plenty busy with his wife and daughters. Andy is also prone to running nearly any distance, with any fellow runner. Stop by with your running shoes on, anytime.

Wm. Roger McPherson

Roger McPherson founded Tengam in 1972, after developing and engineering a convergence-ring magnet for the television industry. It was molded along with a part produced by McPherson Plastics, a family-run plastics business. Roger improved the manufacturing process and met the challenge of producing an industry first: injection-molded magnets. This leading innovation had a strong impact in the marketplace and the magnet industry. Roger was quick to start developing better ways to produce parts using complex materials and innovative molding process techniques. For over 40 years, Roger continued to expand and improve upon his original manufacturing advancements, and watched over Tengam's steady growth.
