Dear Zippy,
I'm sorry to hear about Sandy.  Looking forward to seeing you when you are in West Lafayette next time.

So sorry for your loss! I think of Sandy and his Purdue lab often. Such fond memories working in his lab!

Dearest Zippy,
Phil and I were so very saddened to hear of Sandy's passing. He was such a good person and we enjoyed visiting with you two in Boston a couple years back. May Sandy's memory always be for a blessing. Zichroho liv'racha. Karen and Phil Fanwick
