Hannah Judith (Annie Edith) Landau was born on March 20, 1873, in London, where her father, Marcus Israel (Mordecai, 1837–1913), worked as a clerk for the Jewish community. Annie’s mother, Chaja Kohn (b. Bavaria, Germany 1853–d. 1923), was his second wife. He had five children by his first marriage and during the forty years of his marriage to Chaja a further thirteen were born. Of these, Annie was the eldest. Her parents were of the opinion that girls should receive as fine an education as boys, but there was no sufficiently good school for religious girls in London. Thus, at the recommendation of her mother’s uncle, Moses Weisknopf, she was sent to the Orthodox Samson Raphael Hirsch School in Frankfurt am Main, where her teacher was Mendel Hirsch (1833–1900), the son of Samson Raphael (1808–1888). Returning to London, she studied at Greystoke College, a teacher training institution. After completing her studies there in 1892, she took up a teaching position at the Jews Free School, which she held until 1898.
