c.1923 Charlotte Rhead, who had been working at Wood and Sons since 1912, after her father had been appointed art director of the company, designed for the Ellgreave Pottery and had a considerable hand in modernising their designs. Much of her work was sold by Ellgreave under the trade name of Lottie Rhead Ware.
