 The Alice Austen House, also named Clear Comfort, became a NYC Landmark when, as Vice-President of the Friends of the Alice Austen House, under the leadership of Margaret Riggs Buckwalter, Diana Mara Henry lobbied successfully for the city to grant $1,025,000 to restore the house and open it as a museum.Now a National Historic Landmark, the house was inducted in 2002 into the National Trust for Historic Preservation's highly selective group of Historic Artists' Homes and Studios.Besides her photography of the Women's Movement, including paid assignments for the National Commission for the Observance of International Women's Year, Henry chose to photograph many events on her own initiative such as the Women's Pentagon Action in 1980 and the demonstration at the "New York Times" for the use of the term Ms. in 1974, demonstration against decades-long sex experiments on cats at the Museum of Natural History, the 1977 strike at radio station WBAI against Pacifica, and other often obscure events and personalities that she considered historic and that would be unknown to this day without her visual testimony.
