Mrs Pankhurst's Purple Feather: Fashion, Fury and Feminism – Women's Fight for Change (republished 2021 as Etta Lemon: The Woman Who Saved the Birds) is a 2018 book by Tessa Boase (Aurum: ISBN 978-1781316542) about Etta Lemon and her campaign against the use of feathers in hat-making (millinery) which led to the foundation of the Royal Society for the Protection of Birds. This campaign is compared and contrasted to Emmeline Pankhurst's campaign for women's suffrage in Britain, which it pre-dated. Ironically Etta Lemon was an anti-suffragist and anti-feminist.[1][2][3][4]
