  1. I’m am sorry for his family’s loss. He was a wonderful teacher. He taught me genetics and I often think of him 20 years later. He’s why I love the medical sciences and hope to teach my children the same way. He touched so many. Thank you Dr. Ellison!

  2. Dr. Ellison was a great mentor and friend. I would not be the teacher I am today without his guidance. He will be greatly missed. Love and hugs to Sherry and family.
    Sincerely, Megan Reynolds

  3. Sherry, I am so sorry that your beloved husband has passed. He is in peace and without any more pains. God bless.

  4. So disappointed to learn of John’s passing, especially knowing how determined he was to get his health stabilized. His cheerful presence will be missed at future garden club events. My thoughts and prayers are with Sherry and the family.

  5. Sherry and Family I am so sorry for your loss. My memories of John are happy ones. Every Saturday for the past ten years I would look up and see John, Sherry and Happy. I knew my day was going to be a good one. Either John would be leading Happy or Happy leading John. We would BS and have a few laughs. I will miss these times. He will be missed greatly, but never forgotten.
    God Bless you Grasshopper Dr John.

  11. Sherry and family, we are so sorry to hear of John’s passing. He was always a ray of sunshine and inspiration in our lives- we have so many wonderful memories of him. God Bless him and bless you all.

  12. Sherry,

    It was with great sadness that I learned of John’s passing, first through the email sent by Greg Reinhart and subsequently by Lily’s having pointed out the obituary in The Eagle. I will always remember John’s great self-deprecating and ironic sense of humor. His having taught 14,000 students over 34 years at A&M, it is both staggering and inspirational to realize how many young lives he touched in a positive way. I especially remember him sitting in the Biochemistry office chatting amiably with Juanita, and his walking around his office and environs in his stocking feet. He is greatly missed. May you find peace and joy in the knowledge of how many respected and admired John.

  15. I am a current PhD student in genetics and genomics at the University of Missouri and was just telling a friend about how memorable and cool Dr. Ellison’s class was. He was a wonderful teacher. Thoughts and prayers to the family!

  16. Dr. Ellison was both a friend and a professor while I was at A&M. My father father, Dr. Simmons always told me he was not only very bright but had character. Dr. Ellison was instrumental in helping me follow in my fathers footsteps. I can still remember having lunch with him from time to time in the cafeteria. His wit could light up a room.
