On behalf of his students, I would like to say that Dr. Nissenbaum was a God-sent love for us. We missed the opportunity of communicating this to him, in person. I realized that for myself when I first learned about his passing away. I know that Dr. Nissenbaum is still watching over us and I am sure that if we communicate our personal and professional achievements to Sylvia, it will reach Dr. Nissenbaum. Thank you.
