Marjane Satrapi, a French-Iranian author and illustrator, has died at the age of 56 due to 'sadness', a year after the passing of her husband. She was best known for her graphic novel and film 'Persepolis', which recounts her early life in Tehran and her experiences as an exile in Europe. Satrapi was a vocal critic of Iran's theocratic government and a supporter of women's rights and the 'Women, Life, Freedom' movement. She was also a filmmaker and painter, and her work expanded beyond stories connected to Iran, including a biopic about Marie Curie.
