Martha Brookes Hutcheson (1871-1959) was one of the first American women landscape architects to receive professional training. Hutcheson considered fine landscape design an instrument of social change and was inspired to write The Spirit of the Garden (1923) by a Progressive Era zeal. Hutcheson's designs include Maudslay State Park in Newburyport, Massachusetts; the Longfellow National Historic Site in Cambridge; and Bamboo Brook Conservation Center in Gladstone, New Jersey--all now open to the public.
