Glass industry-veteran Dennis Csehi passed away on August 19, 2021. His career included 27 years with Pilkington followed by many years with Spec-Temp/Atwood Mobile Products Inc. in Antwerp, Ohio.

Csehi earned a bachelor’s degree in mechanical engineering from the University of Toledo, and began his career in the glass industry in the late 1960s when he worked for then Libbey Owens Ford as a mechanical engineer. He was involved in technical and operational processes and systems for float manufacturing, glass filming, automotive glass laminating and tempering, encapsulation, insulating and glass fabrication. In 1997, he joined Spec-Temp Inc. as president and general manager.

In 2015 he was appointed managing principal of the Consulting Collaborative’s Western office in Denver.

He became actively involved in the Glass Association of North America (GANA) in 1998, and served as a board member and also a chair of the tempering division. In 2004 he was the GANA president and was listed as one of USGlass magazine’s Most Influential People in August of that same year. In that issue, he shared that he was most influenced by his wife, Shirley, who passed away in 2011, family, friends, business associates and current events.

“Denny was a true leader; soft spoken, introspective and always encouraging his peers and employees,” says Ren Bartoe, who retired in 2019 from Vesuvius and worked closely with Csehi on many GANA activities. “We met at GANA meetings and he was instrumental in getting me to take subcommittee assignments and eventually the tempering division chair. He represented our industry with pride and integrity.”


  1. Dennis was a class act, he’s been missed In the industry. My sincerest condolences to his family.

  3. Dennis was a true glass industry marvel. From working his way to Vice President of Pilkington NA OEM to using his vast and hands-on knowledge to blaze the trail for strengthened glass for the solar power industry and many other specialty applications. His “get it done” attitude and engineering prowess to quietly make it happen, provided many contributions to the industry. Indeed a class act, industry engaged leader and mentor to many people. My sincerest condolences to his family.

  4. Always enjoyed working with Dennis. He was a professional, as well as kind and considerate. Dennis lived and walked the collaborative approach on the job. RIP Dennis!
