French-Iranian author and illustrator Marjane Satrapi, celebrated globally for her autobiographical graphic novel "Persepolis" and its subsequent film adaptation, has passed away at the age of 56. Her death, reported on Thursday, was attributed by her entourage to "sadness" following the passing of her husband, Mattias Ripa, over a year prior. Satrapi, born in Iran in 1969 and later becoming a French national, used her platform to critique Iran's theocratic government and advocate for human rights, particularly women's rights and the "Women, Life, Freedom" movement. Her 2007 film adaptation of "Persepolis," co-directed with Vincent Paronnaud, garnered critical acclaim, winning the Jury Prize at Cannes and earning an Oscar nomination. Satrapi also directed other films, including the biopic "Radioactive" about Marie Curie, and recently curated a collection of graphic stories on the "Women, Life, Freedom" movement. She had previously declined France's Legion of Honour, citing the country's "hypocrisy" regarding Iranian dissidents.
