In the summer of 1918, Major and Superintendent Raymond W. Pulliam established the Women's Bureau, originally directed by Marion O. Spingarn. The Women's Bureau was created to deal with issues involving juveniles, specifically girls, such as delinquency, investigating casework on juveniles, preventive welfare work to curb criminality in juveniles, and the supervision of movie theatres, dance halls, and similar places. Most of the officers in the Bureau in 1920 were trained as school teachers, nurses, or social workers, and included one lawyer. On October 7, 1918, Mina Van Winkle was appointed a police officer in the Women's Bureau. She was known to be extremely outspoken and was an ardent supporter of protection for girls and other women during the law enforcement and judicial process. In January 1919 Van Winkle became director of the Women's Bureau, a post she held till her death in 1932.
