It has been my intention to present pictures of the people I write about here, but I don’t have any genuine pictures of Duncan. We were often working back to back, or he was way out in deeper water, or over a rise in the terrain, or later in his career, on another continent.

On my last day with him, in July 2016, just before he left the hospital to rest at home with his wife Hyunmi for his final days, he wanted to look at pictures – his, mine, others’. He was a uniquely patient viewer and reader of photographs, noting more than once over the years that “photographs reveal their meaning over time.”

The very last picture that day, one of my old ones from a time before we had met, held him for quite a while, even though he was clearly fading. After his many detailed and encouraging comments, just when I thought he was done with it, he looked up brightly and laughed, “Hey! There’s a third dog in this picture!”
