She grew up in Paris and moved back to London in 1847. In 1851, her father acquired a country estate in Aston Clinton where she lived with her family Along with the sister Anne, she taught to the poor in the Jews' Free Schools around Aston Clinton, and wrote the book The History and Literature of the Israelites. While she was from a Jewish family, her social background was very Christian. In 1877, she married Cyril Flower, a property developer and Liberal Party politician who later became Lord Battersea. They had met in 1864 through his friendship with her cousin, Leopold de Rothschild. They had no children. In 1888, Lord and Lady Battersea acquired two cottages at Overstrand, a village near Cromer, Norfolk, for the purpose of creating a holiday home. In 1897 their architect, Edwin Lutyens, rebuilt and joined the cottages to form a large mansion in extensive gardens, The Pleasaunce. The gardens were developed between 1902 and 1930 by Lord Battersea and his wife. Lord Battersea died in 1907.
Lady Battersea was engaged in temperance movement in the United Kingdom, taking the pledge in 1894, and joined the British Women's Temperance Association. Her political engagement was in part motivated by suffragette Fanny Morgan, and propelled her into the reform movement of women's prisons in England. After scandals of child prostitution committed by East European Jews hit the UK press, she co-founded the Jewish Association for the Protection of Girls and Women in 1885 as the Ladies' Association for Prevention and Rescue Work, a distinctively Jewish association to shelter and support Jewish immigrants. The JAPGW turned Jewish women immigrant into British feminists, setting the groundwork for the futureUnion of Jewish Women. The JAPGW also set up the Industrial Training School which trained women to become domestic servants, matrons and home managers. She led the JAPGW until the early 1920s, participating in international meetings and coordinating international rescue operations. Lady Battersea also turned her London apartment and Overstrand compound into shelters for unmarried mothers and women rescued from the prostitution. Her close ties with the International Council of Women helped her fight off the reluctance of the Jewish higher society to admit that a Jewish prostitution problem existed. After joining the executive committee of the National Union of Women Workers, she became the union's vice-president in 1896, and its President from 1901 to 1903. She remained in the executive committee until 1919, and was made Honorary President of the union after that date. Through her work, she was instrumental in the emergence of conscious Anglo-Jewish feminism. Lord and Lady Battersea were noted for their philanthropy towards working-class people. She was appointed by the Government to the board of Aylesbury Women's Prison.
