I have always treasured the memory of meeting Spencer when he and his wife Linda hosted an evening for the Ojai Poetry Festival. We had a marvelous, long conversation, and I was in awe of actually speaking to the person who'd invented such a staple of my own and everyone's work life. (I mark the poems I'm going to read at an event with the ubiquitous colored flags, changing them from reading to reading.) He was gracious, warm, an engineer who loved poetry, and a walking medical pioneer as well. It was only one evening's conversation, but memorable for a lifetime. My deep condolences to those who knew and loved him.
