Devens was born on 17 May 1857 in
Ware, Massachusetts, the daughter of Arthur Lithgow Devens and Agnes Howard White Devens. She grew up in
Cambridge, Massachusetts and developed an interest in photography sometime in early life. She had a strong interest in printing techniques that could be manipulated by the photographer, including ozotype,
gum bichromate and
platinum printing. She mastered the gum bichomate process so well that she gave a lecture on it to the Cambridge Photographic Club in 1896. At some point before her mid-30s, Devens met Boston photographer
F. Holland Day, who influenced her career through encouragement and advocacy of her work. He personally submitted five of her prints to the London Photographic Salon of 1898 and was responsible for introducing her to photographer
Alfred Stieglitz, with whom she would regularly correspond for many years. Day also promoted her work in his lecture "Photography as Fine Art" at the Harvard Camera Club in 1900 and included several of her prints in his 1901 exhibition "The New School of American Photography." She is not known to have engaged in any photographic activity after 1905. Devens died on 13 March 1920 in Cambridge. ==References==
