Caroline Emma Criado Perez (born 1984) is a British feminist author, journalist and activist. Her first national campaign, the Women's Room project, aimed to increase the presence of female experts in the media. She opposed the removal of the only woman from British banknotes (other than The Queen), leading to the Bank of England's swift announcement that the image of Jane Austen would appear on the £10 note by 2017. That campaign led to sustained harassment on the social networking website Twitter of Criado Perez and other women; as a result, Twitter announced plans to improve its complaint procedures. Her most recent campaign was for a sculpture of a woman in Parliament Square; the statue of Millicent Fawcett was unveiled in April 2018, as part of the centenary celebrations of the winning of women's suffrage in the United Kingdom. Her 2019 book Invisible Women: Exposing Data Bias in a World Designed for Men was a Sunday Times bestseller. Source: Wikipedia (en)
