Dieter was a wonderful mentor to me as a physics major at Temple in the early 1990s. He kept my excitement for astrophysics alive, even though there were no astrophysics classes at Temple, taught me a lot about physics, encouraged my efforts in the Honors program, and in general made a large, urban school feel personal and welcoming. I still fondly remember one time he told me about reading Chandrasekhar's book on stellar structure and then taking the time to explain to me how one could use...

Dieter literally shaped the person I am today. I was one of the first batch of Honor's students under Dieter and Ruth's partnership.

Dieter Forster What an impressive man, what a rich life. Among all his accomplishments and exuberances and joyful ways of being present in life, there´s one that stands out for me. That is, he was a wonderful master of conversation. Dieter could talk to anyone about anything. How enjoyable it was just to engage in conversation, and how comfortable he made it. This is a lost art in our time, but never with Dieter. What a wonderful presence, and we will miss him greatly.

It was always a pleasure coming to Honors and hanging out with Dieter and Ruth. It was my distinct honor to protest when the administration ousted Dieter from Honors for his passion and commitment. It was a protest joined by so many and we also did it out of love and intellectual commitment to the program he and Ruth initially built. I smile everytime I am in the wonderful Honors' spaces that continue to. be a site of curiosity, friendship, and play at the heart of Temple's campus. Dieter...
