Minor was reared in Columbus, Texas and returned to San Antonio in 1944 to work at Kelly Air Force Base. During her time as a civilian working on the base, she was a fighter for equal treatment of employees.
From 1986 to 1996, Ms. Minor was the president of the San Antonio Branch of the NAACP. During her time as president, she would organize the San Antonio Annual Martin Luther King, Jr. Day March Celebration. The march has grown to become the largest annual civil rights celebration in the country with over 100,000 participants. After retiring from her post as president in 1997, Minor was approached by her community and asked to re-assume the post. She was again reelected in 2003.
