Clark Hacienda Care Center 76 Fenton Street Livermore, California 94550 Dear Paul: Your family was kind enough to remind me that your centenary is just about to ar- rive and this gives me the very happy pleasure of renewing my association with you. As you know the years that I spent at Wisconsin -~ not to compare with yours -- were among the most productive in my labora- tory career and I had a most happy and fruit- ful time there. I have not had any oppor- tunity to see-you since you retired but I have had frequent occasion to consult your historical writings. I know that you have been deeply inter- ested in the history of this institution, nearly since its founding, and so I thought that the enclosed memento might be particu- larly meaningful to you. With my earnest best wishes, Yours sincerely,
