Martha Ann Maxwell (née Dartt 21 July 1831 – 31 May 1881) was an American naturalist, artist and taxidermist. She helped found modern taxidermy. Maxwell's pioneering diorama displays are said to have influenced major figures in taxidermy history who entered the field later, such as William Temple Hornaday and Carl Akeley (the father of modern taxidermy). She was born in Pennsylvania in 1831. Among her many accomplishments, she is credited with being the first woman field naturalist to obtain and prepare her own specimens. She was inducted into the Colorado Women's Hall of Fame in 1985.
