Yousuf Karsh's Portraits in Boston

Jacques Cousteau, 1972
"In his wetsuit, his profile reminiscent of a thirteenth-century mystic, Jacques Cousteau reminded me of a medieval seer. As I photographed this knight of the twentieth century, I was fascinated to learn about his underwater research. "It is the key to human survival," Cousteau said. He warned that man is gravely endangering this vital resource. All land pollutants eventually find their way to the oceans and "we risk poisoning the sea forever, just when we are learning her scenic art and philosophy, and learning to live in her embrace."
