Mina Caroline Ginger Van Winkle (March 26, 1875 – January 16, 1933) was a crusading social worker, suffragist, and groundbreaking police lieutenant.
From 1919 until her death in 1933, she led the Women's Bureau of the Metropolitan Police Department of the District of Columbia (in Washington D.C.), and became a national leader in the protection of girls and other women during the law enforcement and judicial process.
Her provocative statements about gender and morality in the jazz age brought her further national attention.
