  • We’re friends with Ernie and Irene early in my career with Du Pont sorry to hear the sad news prayers to Ernie’s family. Irene please accept our Condolences. RIp

  • Ernie was a solid old school engineer who loved hands on work who loved his job and showed it. In my 20+ years supporting the DuPont Edgemoor site Ernie was the filtration expert we regularly consulted. He’d eagerly come out to the site and ‘doctor’ us on what we needed to do to fix things….he was right! Thanks for all your help over the years Ernie and you taught me a lot about equipment, people, and how to be fully engaged to get to the root of the problem. Rest in peace Ernie.

  • Dr. Mayer is an important figure in industrial filtration and the filtration community as a dedicated member and contributor for the American Filtration and Separations Society. He had been attended and chairing/presenting at every single AFS Conferences until 2014 when his health prevented him from travelling. I recalled everyone was asking “Where is Dr. Mayer” at that conference. I had opportunity working with Dr. Mayer closely for many years. He was a mentor and good friend. He last reached to me in 2021 asking if we were ok with the Covid as he saw the vaccination rate was low in our state. He will always be remembered!

  • It was an honor to work with Ernie. His great expertise and excellency lead from a successful business relation into a very good personal friendship. What an amazing person! I am grateful to have had the privilege of knowing him.
    I will always remember the wonderful times we had together and will be thankful for this.
    My prayers and condolences are with you at this difficult time.

  • Dear Family,
    I am a member of the Hi Railers Train Club and have known Ernie since I joined in 2010. He was a great guy, always wanted to talk about rrains and really cared about the guys in the club. I always had a talk with him at every meeting and he was such a nice guy! I am going to miss him. It was sudden, I guess, because I was surprised to hear about his passing. Please know that he will be missed. Ernie is now with his dear wife. My condolences to his children and grand children. May God bless you all in your sorrow.
