Katherine Bleecker was a pioneering professional camerawoman, who used her own personal camera equipment. She made three documentary films for the Joint Committee on Prison Reform, on location at New York state prisons,
Sing Sing,
Auburn, and
Great Meadow:
A Day in Sing Sing (1915),
A Prison Without Walls (1915), and
Within Prison Walls (1915). The films were used in lectures about prison conditions and
prison reform. "I've had a varied experience with my pictures," she explained. "I've been up in a flying machine, have taken from tugboats and automobiles, and always there are plenty of bystanders ready and eager to jump in and play mob or be shot." In 1916 she directed "Man and Millionaire", a film scenario written for a contest in
The Pittsburgh Press. In 1918 she completed
Madame Spy, a film starring
Jack Mulhall,
Wadsworth Harris,
George Gebhardt and
Claire Du Brey. She also advertised her services as available for documenting "children and social events ... factories and machinery." She filmed the 1918
Memorial Day parade in
Nutley, New Jersey. She also made some of the first "society films," a novelty version of club theatricals, with titles including
The Perils of Society,
Skeins of Destiny,
The Flame of Kapthur, ''The Smuggler's Revenge
, Gloria
, A Question of Fortune
and A Romance by the Sea''. Bleecker would create the film, with wealthy amateurs playing the roles for their friends' entertainment or for fundraising events. "I am going to prove that theater managing is like housekeeping – a woman's job", she quipped. Also during
World War I, she made films for the
American Red Cross. ==Later life==
