Ruth Bader Ginsburg's early career experiences shaped her advocacy by highlighting the persistent gender discrimination in the legal profession. Facing barriers in the 1950s, she struggled to secure employment despite her qualifications, influencing her later commitment to women's rights. As co-founder of the Women’s Rights Project at the ACLU, Ginsburg successfully argued landmark cases that advanced gender equality. Her legal strategies often relied on the principle of equal protection under the law. These experiences not only shaped her judicial philosophy but also reinforced her status as a trailblazer for gender equality in America.
