At Hamlin

You have my deepest condolences. I spent almost 20 years working with Dave at Hamlin. I was an engineer and spent much time with him back in the lab. He was skilled and professional; a ready source of experience and good advice. We had many good conversations on various things over the years. He was one of the high points of my time there, not just professionally but personally. Sincerely, Steven R. Stuve

I was shocked when I heard that Dave died. He and Mary Ann were a perfect couple!. His family will be in my prayers.🙏🙏🙏❤️❤️❤️
