My condolences to the entire family. Jack was my first supervisor at NASA and I will never forget the guidance he gave me. He was also a good friend and I admired his courage and purpose in life. His peace be with you.

Jack was my first supervisor when I came to work as NASA. I worked for him for 10 years and he was the best manager I ever had. For me he represented that great engineering and management culture that was NASA in 1970’s. As an engineer, he was the best one I ever worked with and he taught me many great lessons that I have used throughout my career. My sympathies and prayers are with his family and all who knew him. He was a man of great caring, integrity, as well as and outstanding mentor and role model. He will be greatly missed by all.

Much love and with deepest condolences,

Jack lived an admirable life indeed. He was a major contributor in many ways. Thoughts go out to his family and dear friends at this time. May they all cherish his memory and learn from his good example as they await a promise of reunion as written at Revelation 21:3, 4.

Sorry to hear my ex roommate died. We had many good memories of our younger years, but, unfortunately, we never got together later as we had hoped. Perhaps we’ll meet in the beyond.
