Dear Bill, So sorry to hear this news and the passing of another wonderful scientist and contributor in our field. It was very interesting reading your obituary. May his soul rest in peace.
I first heard about John and Abraham as a graduate student and later on when I joined Sung-Hou for postdoc training. I was interested in their holographic method for x-ray structure determination as I was dealing with a case where I had density for the partial molecule from molecular replacement and experimental structure factors for the entire protein/DNA complex and was looking at ways to recover density for the missing portion in addition to experimental phasing.
