As our community progresses through the years, we are deeply saddened to learn of the passing of our friends and colleagues. We remember our associations with these friends tenderly, and we extend our love and sympathy to their families.
Professor Ramez Elmasri passed away on May 14, 2022. He was a wonderful colleague and friend to many in the conceptual modeling community. Quite a few of us have used his textbook, Fundamentals of Database Systems (with Sham Navathe), for years. Ramez was the program chair and helped organize the 1993 ER conference at his university, The University of Texas at Arlington. We recall many fruitful discussions and collaborations with him, and we will miss him. We express heartfelt condolences to his family.
Reind van de Riet
Professor Reind van de Riet passed away unexpectedly on December 18, 2008. Professor van de Riet served long and well in many professional capacities. In the conceptual modeling community, Reind was a true friend and a collegial associate for many decades. For the ER conference held in Barcelona in October 2008, he convinced Elsevier to financially support several activities, including the first Peter Chen Award (which recognizes outstanding contributions to the ER community through research, mentoring and service), a best paper award, and an extravagant reception dinner in a restaurant overlooking the Barcelona Harbor. Academically, Reind made a number of substantial contributions. He edited the special jubilee issue of Data & Knowledge Engineering, November 2008, in which he also published a 25-year look at his Mokum system for correctly designing information systems and how these designs can be translated into implementations. As a service to others in the community, Reind was a co-founder and a long-time Editor for Europe of Data & Knowledge Engineering. Personally, his smile and friendly demeanor cheered all of us at the many conferences he attended. Recently, he shared his organ talents with us, playing an organ concert for the participants of UNISCON in Villach, Austria. We express our heart-felt condolences to his wife and other family members. We will miss our dear friend.
Professor Yahiko Kambayashi served long and well in many professional capacities. Academically, he achieved much, receiving many awards and appropriate recognition for his contributions. We honor him particularly for his service to the ER community. He was chair of the 17th International Conference on Conceptual Modeling (ER'98), and was a member of the steering committee for many years.
