I just learned of Cookie's passing a couple of days ago. My sincerest condolences to the family.

I worked with Cookie while I was chair of the ABET Computing Accreditation Commission in 2007-08. He was one of our commissioners then. I fondly recall his having chaired an unusual accreditation visit, which was at Cal State San Bernardino. The visit was interrupted by wild fires. Cookie trooped on, however, and successfully completed the work with his team. At our summer commission meeting, I remarked about my poor choice of sending someone named "Cook" into a fire zone. He was recognized at the meeting for his diligence in the face of unusual circumstances, and presented with a Smores kit for his troubles.

Everyone appreciated the professionalism that Cookie always displayed and the care with which he exercised his responsibilities, no matter the situation.

I met David, his first wife, and his 2 daughters in 1987. We were both Air Force Captains and were both students in the PhD program (Computer Science) at Texas A&M University. I arrived a year before David and I graduated a year before David. I was single at the time so I truly appreciated the way David and his family provided me with a very special "home away from home." Being treated like family at that time was just what I needed. My deepest condolences to his entire family. The last time I talked to David on the phone he expressed how proud he was that both daughters are happily married to their first husbands. I will miss talking to him. Again, deepest condolences.

Deb and family~ My heartfelt condolences in the passing of such a wonderful gentleman as Dave was. He was the most wonderful, open hearted and generous man. His stories were legendary and his laughter so infectious. It was an honor to know him for the short years we lived near each other in Albuquerque, NM. He was so proud of his girls, wife, and his extended family. He will forever live in our hearts.

Ah, David. What a sense of humor! And what a quick wit. I had the privilege of calling you my brother-in-law, although at times I felt more like your sister. That in-law stuff didn't quite capture it. If you read this from heaven, then know that I appreciate your loving my sister. You were loyal to a fault at times! But no one ever questioned your heart's motives. Enjoy heaven. There are no bad jokes there, you know!

We are so sorry to learn of Dave’s passing. He was such a fun person to be around and share time with. We were stationed with David and his first wife at Keesler AFB in Biloxi MS. We were neighbors and we became more like family. Still remember that smile and laugh. He left many footprints across many hearts- ours included
May God be with all of you.
