Thursday, May 02, 2002 7:36 AM Dear Thane, I was surprised and very saddened when I learned of the David's death much after the fact, and I am still curious about exactly what happened. In any case I can explain the manuscript and correspondence you found. I was project director on an NSF grant for COMAP to develop materials for high school students by distingished research mathematicans. David agreed to write a module about box packings for the series. He started work and if I recall sent me a first draft of the first chapter (I am not sure where that is now, or if I even still have it) but at some point a believe wrote me that he would be unable to finish or do anymore work. At that time, and even now, there is no unified treatment that I know of at a "low" level about box packings. Is it your plan to put these unfinished materials up on the web? Can you send me a photocopy of what's there? How did you know David? Best, Joe -- Joseph Malkevitch Department of Mathematics York College (CUNY) Jamaica, New York 11451
