Etta Agnell Wheeler (1857 - December 5, 1921) was the rescuer and advocate of Mary Ellen Wilson, whose infamous abuse story led to the creation of the New York Society for the Prevention of Cruelty to Children. Wheeler was also influential in the society’s creation because she convinced future founder of the society, Henry Bergh, who at the time was founder of the New York Society for the Prevention of Cruelty to Animals, to take on the issue and spearhead the case.
