If belief in a person means friend, then it is so. May God bless you.

Bill and I were in the same class year, 1958, at University High School. We both played on the school basket ball team. I remember him as competitive, but willing to pass the ball to a teammate who was open. In our senior year we were in a special math class. We learned differential and integral calculus and infinite series. I learned later the content of the class was usually taught at the Sophomore level at the university. It was in this class that I experienced Bill as always in good...

I am saddened by our loss. My life was enriched by spending time with you and the family. Karen was a great friend of mine in high school and college. I have fond memories of my time with your family, from skiing in Breckenridge, the trip to Santa Barbara, going to Milwaukee and Cub games with Karen and Chuck. The picture above transported me back to the high school days. That's exactly how I remember you. Karen, Chuck, and Marge, you have my deepest condolences. Thank you for the...

Bill, you are such an important part of our physics community. You built something truly special with the Fermilab theory group, and I feel so lucky to have spent time there. Beyond being an extraordinary physicist, you embodied something we too often forget: the importance of making a workplace welcoming to everyone.

I often thought Bill was like my own dad over the years. The Bardeens are very dear friends of mine from childhood days and have a cherished place in my heart. They will always be a part of my extended family. Thinking of Marge, Karen and Chuck during these sad times... though knowing that Bill´s legacy will always carry forth in his contributions that he´s made in the scientific world and embedded in the wonderful spirits of the family he´s left behind.

What a lovely man and family! The Bardeen family contributions to science will be lasting.

The world is going to miss you Bill, I know I will. Hope you can find some good puzzles to work on.
