Sydney Taylor (October 30, 1904 – February 12, 1978) was an American author. She was born Sarah Brenner in New York City to Jewish immigrant parents. Her parents and eldest sister Ella emigrated in 1900 to the United States and settled in the Lower East Side of Manhattan, as many Jewish families did. Her stories based on life in her large family are chronicled in a set of five books known as the All-of-a-Kind Family series. "During the second half of the twentieth century [the books in the series] were the most widely known books about American Jewish children."
