Ruby M. Rouss (3 December 1921 – 8 May 1988) was an American citizen born on Saint Croix in the US Virgin Islands. Her career was marked by a series of firsts. She was the first Virgin Islander in the Women's Army Corps (WAC), first African-American woman to serve on General Eisenhower’s staff, and first black woman assigned as a permanent staff of Supreme Headquarters Allied Powers Europe. After a 20-year military career, she retired from service and became the first woman parole officer in St. Croix. In 1973, she was elected as one of the first women to serve in the Virgin Island's legislature. In 1981, Rouss served as the first female President of the Virgin Islands Legislature, becoming the first black woman to lead a legislature in the United States. She was elected to serve a second presidency of the Senate in 1987 and died the following year. Posthumously, she was inducted into the Virgin Island's Women's Hall of Fame and a housing project in St. Croix was renamed in her honor.
