Interesting bio of the artist here and here. Berenice was a photographer, sculptor, and a poet in the 1920's, and became a darkroom assistant to Man Ray before starting her own studio in Europe.
During a visit to New York in 1929, she was inspired by the potential of a photographic project highlighting NYC architecture and design. This evolved into her CHANGING NEW YORK position via the Federal Art Project.
"A sincere thank you to Peter Trayhurn for his time, patience and passion throughout the shoot. As the day progressed Peter shrugged off tiredness to assist any way possible in addition to sharing a very personal insight into that life-changing day almost four years ago. A subtle reflection of his true spirit and generosity.

Thank you also to (retired) Captain Peter Rietdijk for his time and beautifully spoken words."
