By the late '60s we were both involved in radical politics and underground newspapers and crossed paths at demonstrations and other radical events in DC and NYC and San Francisco. I hadn't seen him in years, decades probably, and we never were close friends, just knew each other through Lee when she was still alive and through radical alliances. But I always dug his generous spirit and his creative chops.
I couldn't find a photo of him when we first met, but I think his character "Trashman" comes closest to defining his aura when we first met, so I'll let that stand in for him.
[Thought I had included a link to the SF Chronicle obit but guess my post op brain thing was fooling me. Thanks to old friend Bob Berner for hipping me to it. Here's the link.]
