Condolence: Our sincere condolences to Dr Schuster's family and colleagues from those of us in Puerto Rico who have known him and his important contributions to the field of addiction for a number of years. We appreciated his support to our island's initiatives on medication assisted treatment on our inmate population. He will be greatly missed. Angel Gonzalez, MD Carmen Albizu-Garcia, MD

Condolence: Bob was a man who touched many of us through his own research work, and support of others while at NIDA, his mentorship of students, his long friendships, his advocacy of good causes, and his warmth and winning generosity of spirit. He was "well rounded" - he loved not only his family and friends but his cats and good jazz. A special person who will long be remembered and missed.

Condolence: I had great admiration for Bob and his work. He was truly dedicated to solving the problems of addiction. He was always willing to discuss issues with everyone and was inclusive of everyone as well. I send my sincere condolences to Chris-Ellyn and the family. He will be missed. Marilyn Huestis
