Dear Mrs. Schmitz and family,
I learned this news while I was attending this year's AIChE annual meeting in San Francisco. In fact, I was hoping I would have met Dr. Schmitz at the meeting.
Dr. Schmitz was the best teach I ever had and I learned all know from him. He was so patient and helpful guiding my research that the basic knowledge I gained is still relevant today. Also, I really treasured those visits to your house during the holidays while I was a graduate student at UI. I still remembered a copy of Jan's letter sent to President Nixon at 10 and a signed picture of Babe Ruth hung on the basement wall where we played pingpong and had the delicious food you prepared. You hospitality really meant a lot to us when we were so far away from home!
Please accept my deepest condolence and take a good care of yourself and the family.
