I've just discovered Dorothy!
Wikipedia will tell you that this amazing and wonderful woman "is a photographer based in London, known for her portraiture, street photography, early adoption of colour, and photography of London and Paris; she is considered one of the doyennes of British photography."
Do take a couple of minutes to watch these short interviews with Dorothy (now aged 96) from 2012 and 2016. From what I have seen of her work so far I just love it but I need to learn more! Mmmm...I feel the need to purchase a new photobook!
