Adriana Olguín

She was appointed Minister of Justice in 1952, during the government of Gabriel González Videla. Though she served only a short period of time, she is credited as being the first woman ever to hold a cabinet post in Latin America. Shortly after Olguín's appointment as Minister of Justice, María Teresa del Canto was named Minister of Education (1952–53), though women did not play a significant role in Chilean government until the 1990s.

Between 1946 and 1953 she worked in the Women's Bureau. In 1955 she joined the board of the Bar Association and during the 60's she was legal adviser to the Comptroller General of the Republic. She later joined the State Council convened by the military regime between 1981 and 1989.
