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.
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.
[2] Born in Brazil, she is the daughter of Carlos Criado Perez, an Argentinian-born businessman and former CEO of the Safeway supermarket chain in the UK, and Alison, an English registered nurse who has worked with Medecins Sans Frontieres on a number of humanitarian aid missions.
[10] Since then, she worked, in 2012, as an editor for an information and networking portal of the pharmaceutical industry[9] and in 2013 was in the process of completing a master's degree in Gender Studies from the London School of Economics.
[4] In a June 2013 profile by journalist Cathy Newman in The Telegraph, Criado Perez commented: "the culture we live in is made up of little tiny sexist acts which you can just ignore but when you think of them collectively you start to see a pattern.
"[22] Jane Austen was not her preferred female historical figure, but Criado Perez still approved of the choice: "She spent her time poking fun at the establishment.
[20] In an article in the London Evening Standard in September 2017, Criado Perez wrote that she would donate her first "Austen tenner" to her local women's shelter: "It feels like the right way to end this chapter of my life".
[27] At this point, Criado Perez said that she was receiving about 50 such threats each hour,[28] and found somewhat inadequate the suggestion that she fill in an on-line form for Twitter detailing the behaviour she had experienced.
"[30] While she felt it was taking over her life,[31] Twitter at the time was assuming no responsibility for the content of tweets, merely advising users to contact the relevant authorities.
"[33] The Labour MP Stella Creasy, who had been involved with Criado Perez in the bank note campaign, was amongst those who suffered similar criminal harassment.
[34][35][36] An on-line petition calling on Twitter to introduce a button to enable site users to report abuse had gained 110,000 signatures by 2 August.
[28] Criado Perez did not participate in the Twitter silence organised by Times journalist Caitlin Moran for 4 August to persuade the social media site to change its policies.
[45] When asked on the BBC's Newsnight programme in early January whether she was surprised that one of the convicted Twitter abusers was female, Criado Perez said that the woman in question had internalised misogyny already rampant in society as a whole.
[53] Her open letter to the newly elected London Mayor Sadiq Khan, published by The Daily Telegraph the following May, was signed by a number of prominent women.
[60] Announcing the plan for the statue of Fawcett, Khan said: "It's simply not right that nearly a century after women's suffrage, Parliament Square is still a male-only zone, and I'm thrilled that this is soon to change thanks to Caroline's inspired campaign".
The book has been translated into many languages, including French, German, Dutch, Italian, Spanish, Finnish, Portuguese, Romanian, Russian, Persian, Swedish, Icelandic, Danish, Greek, Lithuanian, Estonian, Czech, Slovak, Ukrainian, Turkish and Chinese.
[63] For her successful activism over depicting women on bank notes, Criado Perez won the human rights campaigner of the year award from the pressure group Liberty in November 2013.
[65] Criado Perez was appointed an Officer of the Order of the British Empire (OBE) in the 2015 Birthday Honours for services to equality and diversity, particularly in the media.
