Mattie Edwards Hewitt (1869–1956) was an American photographer of architecture, landscape, and design. In 1901, she met Frances Benjamin Johnston, already an established photographer, and started a correspondence with her; she moved to New York to work and live with Johnston in 1909. They established a firm called the Johnston–Hewitt Studio in New York City, with Johnston working as the photographer while Hewitt was the darkroom assistant. Their partnership broke up in 1917, after which Hewitt set up a commercial photography studio of her own, taking pictures for designers and architects, and recording interior and exterior views of homes, commercial premises, and gardens, primarily on the East Coast. This photograph of Hewitt was taken by Johnston.Photograph credit: Frances Benjamin Johnston; restored by Adam Cuerden
