Willebrandt began her political career by campaigning for candidates
and became a member of the California Republican State Central Commit-
tee which, combined with her legal skills, led to her appointment in 1921 as
a U.S. assistant attorney general by President Warren G. Harding. In charge
of Prohibition enforcement, taxes, and the Bureau of Federal Prisons, her
responsibilities included coordinating the enforcement programs of the
Treasury Department, the Coast Guard, and state and local law enforcement
agencies. Willebrandt became most widely known for her prosecution of
Prohibition cases, leading New York governor Alfred E. Smith to refer to her
as “Prohibition Portia.” She responded:“It is not particularly gratifying to be
thought of merely as a Nemesis of bootleggers, a chaser of criminals.” Her
first big cases came in 1922, when she broke two southern rings, one in Sa-
vannah, Georgia, and the other in Mobile, Alabama, in which Congressman
John W. Langley of Kentucky was found guilty. Willebrandt developed a
novel strategy for enforcing the Volstead Act when she decided to use in-
come tax evasion as a way to stop bootleggers. She preferred enforcing tax
laws because, as she said: “They require detached and abstract thought, an
intellectual exercise of which women were once thought incapable.”
Willebrandt aggressively pursued those who broke the law, filing be-
tween 49,000 and 55,000 criminal and civil cases annually. In these cases,
she helped establish the constitutional validity of the Volstead Act and
other laws through U.S. Supreme Court decisions. Of the thirty-nine cases
she argued before the Court, she won thirty-seven. By 1929, of all the
lawyers who had argued cases before the Court, she ranked fourth in the
total number of cases she had presented.
With prisons filling with Volstead violators, the need for additional
space in them grew, as did the need to review the related policies. Wille-
brandt began by calling for a federal women’s prison, for which she sought
support from the Women’s Joint Congressional Committee (WJCC).
With the WJCC’s help, she found support from the League of Women
Voters, the Woman’s Christian Temperance Union, the General Federa-
tion of Women’s Clubs (GFWC), and several other groups. She also be-
lieved that young, male, first-time offenders serving their sentences in
prison were further corrupted by the exposure to more experienced law
violators and that a federal reformatory for them was needed. By enlisting
the support of the Young Men’s Christian Association, GFWC, American
Bar Association, Kiwanis Club International, and other groups, Wille-
brandt succeeded in creating a federal reformatory. In addition, she
sought to improve prison conditions and to provide work within prisons.
Her first task, however, was to identify and remove corrupt and incompe-
tent prison officials by planting government agents posing as inmates
within the facilities. With the support of GFWC and others interested in
