Growing up in a community of artists in the Essex village of Great Bardfield, Rosthenstein comes from a family of artists and creators. Her father was the late Michael Rothenstein, the print-maker, and her mother is Duffy Ayres the painter. Her grandfather was William Rothenstein who ran the Royal College of Art and served as an official British war artist. Her uncle, John was a Director of the Tate Gallery, and her brother, Julian, is a designer and founder of the Redstone Press. Her influences include Bacon, Matisse and Braque but the work is unique, very much her own expression of sardonic wit, expression, curiosity and gesture.
"At a visceral level, these are paintings that reward a great deal of looking. If their surface is deceptively decorous – mellow colours and sculptural shapes – they are also uncanny, both familiar and strange." - Deborah Levy, 2017
After working for ten years as an actor, Rothenstein has been painting full-time since 1982, exhibiting regularly across London, and for the last two years has regularly designed covers for the London Review of Books.
