i am so, so sad to hear this news. of course, not unexpected, but extremely sad nonetheless. much too brilliant and good to leave so soon. he did, however, survive much longer than most with that type of cancer. i'm sure he sacrificed a great deal of quality to his life as a result. may he be at peace, especially knowing that he contributed so much to this world, especially in his charitable giving.
my sincere condolences to his friends and family.
