Born in Edgefield, South Carolina, he later moved to Mississippi and represented Hinds County in the state legislature from 1859 to 1861. He was the only child of Henry Mims and Susan Burr Read of Edgefield, South Carolina.
During the United States Civil War, Major Mims served under General John C. Pemberton and saw action in the Battle of Jackson, Champion Hill and Vicksburg Campaign. Shortly after those losses, he joined Joseph E. Johnston's staff and shared a friendship and business interests until Johnston's death in 1891.
After the war, he became southern manager of the New York Life Insurance Company (since 1868) and he was charter member and served 20 years as president of the Capital City Club. Following his death in 1906, he was buried in Westview Cemetery. In observance of his death, Atlanta's City Hall was closed for one half day, and free carriage rides were offered from City Hall to the Westview Cemetery.
Politically he was an old school Democrat and he was elected mayor of Atlanta in October 1900. The election came in the midst of Atlanta's streetcar war; he was supported by Joel Hurt (Atlanta Consolidated Street Railway Company) and opposed by Henry M. Atkinson (Georgia Electric Light Company).
