Mary Campbell Johnson was one of the first three females to practice law in Georgia.
[2] She was married to Minton Rollingsworth Johnson, who worked as a customs collector at the port of Brunswick.
Since women were not permitted to take the examinations, Johnson had to wait until a legislative act was passed in order to give women that right.
[3] Once the law changed, Johnson passed her examination, and was admitted to practice law in Georgia in 1916.
Johnson was the third woman, as she was preceded by Minnie Anderson Hale and Betty Reynolds Cobb respectively that same year.
