This self-portrait of Pierre Petit (left) reminds me that I am overdue for a haircut. Petit, who lived from 1832 to 1909, photographed many of the important events and artists of his time. He was the official photographer of the International Exhibition of 1867. He reported on the construction of the Statue of Liberty. He photographed the Siege of Paris. He was the first to attempt underwater photography.

I’m attaching his portraits of Berlioz and Delacroix, then I’m off to be shorn.
