Lois Greenfield is an American photographer best known for her unique approach to photographing the human form in motion. Born in New York City, she attended Hunter College Elementary School, the Fieldston School, and Brandeis University. Greenfield majored in Anthropology and expected to become an ethnographic filmmaker but instead, she became a photojournalist for local Boston newspapers. She traveled around the world on various assignments as a photojournalist but her career path changed in the mid-1970s when she was assigned to shoot a dress rehearsal for a dance concert. Greenfield has since specialized in photographing dancers in her photo studio as part of her exploration of the expressive potential of movement.
She has created images for the world's most well known dance companies such as Alvin Ailey, Martha Graham, Merce Cunningham, Paul Taylor, Bill T. Jones/Arnie Zane Dance Company, and American Ballet Theatre. Her work has been published in numerous periodicals, and has been exhibited in museums and galleries around the world. Based in New York City, she gives workshops and lectures in schools around the world.
