Jo Spence (15 June 1934, London – 24 June 1992, London) was a British photographer, a writer, cultural worker, and a photo therapist. She began her career in the field of commercial photography but soon started her own agency which specialised in family portraits, and wedding photos. In the 1970s, she refocused her work towards documentary photography. Many of her works were self-portraits about her own fight with breast cancer. She depicted her various stages of breast cancer to subvert the notion of an idealized female form. During her prolific photography practice, she became known for her politicized approach to her art form, with socialist and feminist themes throughout her career.
