Thomas Erwin Salzer

Thomas Erwin Salzer, 85, of Bedford, Massachusetts, died on July 5, 2026, after 85 years of life spent building things, photographing the world, and making the people around him laugh. He grew up in Brookline and Newton. He lived in Bedford and then Sharon, and has a home in East Sandwich, Massachusetts.

Tom was born on August 26, 1940, to holocaust survivors Dr. Erwin Salzer and Johanna (Herrmann) Salzer, whose family roots were from Germany and Austria. That heritage ran through his sense of craftsmanship and his quiet, exacting way of working through a problem until it came out right.

He earned his degree in Mechanical Engineering from Northeastern University and began a career that would define much of his adult life: engineering. At Raytheon, he rose to Principal Engineer in the company's Optics, Photonics, and Laser division, where he spent 35 years working on the fine mechanics of joining materials together: ultrasonic bonding, laser soldering, aluminum wire bonding for microelectronics, and precision resistor design. These were challenging problems, and exactly the kind Tom loved: intricate, exacting, and essential to work few others could handle.

In 1972, he also founded Hermetric, Inc., which he ran from Bedford. He held seven patents spanning nearly three decades, including one for a high current, low impedance resistance welding device (Centaur, Inc., filed 2002, issued 2004), co-invented with Dennis K. Briefer and George Becker. This one reimagined the resistance welding transformer itself: instead of the standard design, his version could deliver more than 75,000 amperes of welding current while being lighter and more efficient than conventional machines. He approached his work with patience and rigor, and he was still leading Hermetric decades after most engineers would have called it a career.

But the patents and engineering were only part of the story. Tom had a fun, irrepressible sense of humor and a deep well of dad jokes he was always ready to deploy, timed for maximum groan. He was an excellent trap shooter and was an avid photographer, enjoying the machinery of a finely crafted device. His travels took him as far as Africa, where he spent time capturing images of the landscapes and animals he encountered. He played string instruments, and the mandolin was always his favorite: he could often be found with one in his hands, working through a tune in his own corner of the room.

Tom is survived by his wife of 27 years, Elizabeth "Bette" (Chadwick) Salzer; son Stuart (wife Linda); son Scott; his grandson, Garrett; his stepsons, Sean Daly and Michael Daly (husband Alex Arauz); and his stepdaughter, Lynne Daly Finn (husband Dr. Stephen Finn); step-grandchildren Kevin Daly (wife Alison), Brian Daly (fiancé Mariah James), Dr. Caroline Finn (husband Samuel Driggers), John Finn, and Elijah Daly-Arauz; sister Marianne Cornish and brother Ronald Salzer.

He leaves behind a family who loved him, a body of work that shaped how things are built and joined, and a lifetime of photographs and music that carry his eye and his hands forward. He will be remembered for his humor, his patience, his curiosity, and the quiet joy he took in getting something exactly right.

Relatives and friends are kindly invited to attend Tom's visitation on Friday, July 10th, 2026, from 3:00 - 5:00 pm in the James H. Delaney & Son Funeral Home, 48 Common Street, Walpole.

A graveside service will be held at 1:00 pm on Saturday, July 11th, 2026, at the New Riverside Cemetery, 124 Suncook Valley Road, Alton, New Hampshire, 03809.
