Very saddened at the loss of a great person. I remember Dan from the early undergrad days at Swarthmore, when he hatched the idea of starting a company based on commerce on the Internet in 1994. People thought that it was crazy, but Dan had foresight & vision. As Roger said in his eulogy, Dan also impacted my life tremendously.
My wife Judith and I were grateful that he was able to make a wonderful speech at our wedding in California. We remember his big boisterous laugh and generous heart.
