Judy, I fondly remember helping you when you came to Oak Ridge, and working with John. I thought of you both often over the years. We are so sorry for your loss. You are in our prayers.

It was an honor to work for John, one of the smartest, wisest, most decisive, and most quotable leaders I've ever known. Rarely a week goes by that I don't reflect on and apply principles that John taught.

I recall a time I had just begun working for John and I wrote some thoughts for him to consider for a speech he would be delivering. He kindly said something along the lines of "You don't need to write these, I know what I want to say." I told him I felt it was my job to provide him with input, so I did my best to give him something useful; he smiled and said in that case, he would read through what I gave him. Later, as he spoke in front of a packed room (and his speech, incidentally, was much better than anything I'd given him), he paused at one point, made eye contact with me at the back of the room, and with a knowing smile delivered one of the points I had suggested. It was a tremendous feeling to have him acknowledge my work in such a subtle yet definite way.

I had several similar occasions over the time we worked together. Sometimes he acknowledged my good work, and sometimes he coached me on how to improve. Either way, it was rewarding to me to work with and learn from John. My career and my life have been better for it.

John was a mentor to me and together we accomplished many things. Our collective trust in each other… leave it at that.. miss you my Yoda.

John was open to collaboration and outside inputs because he was confident that he and his team were the best, and that any new perspectives would only make them better. He really cared about his people and supported their success, and he was expansive about who he included in the category of "his." I remember him as always smiling, and totally irreverent; I was fortunate to know him.

John was “the gold standard” both personally and professionally. He set the bar high for all of us. He will truly be missed.

As the staff historian for the Naval Historical Foundation I was always impressed with his caring for the well-being of the staff and his interest in engaging with naval historians. He was a great president for our organization.

John was a great boss and great friend. We bid NNSA jobs together and he brought me to the Nevada Test Site from Bechtel London and gave me great assignments. A great job! Living in Vegas, blowing things up in the desert and working for the Admiral.

I once asked John how he should be addressed. He said, “Flag rank and above address him as John. Below flag address him as Sir. You, Bob are below flag rank!”.

He will always be Sir John to me.

Read in peace Sir John.

John was a wonderful friend and mentor. He hired me at Bechtel, at a 7:30 am breakfast, knowing full well I was still half asleep and didn’t really want the job. That was 18 years ago. He always had a kind word and I loved his funny, sporadic emails from wherever he happened to be in the world. The pandemic meant we didn’t share one more lunch together as we had planned. I will miss him dearly.
