[3] It was uncommon for women in the early 1900s to become lawyers, and Napier found it difficult to obtain a job.

After the approval of the 19th Amendment in 1920, which allowed women to vote, Napier was convinced by the editor of the Macon News to run for General Assembly and hence became one of the first two women to be welcomed into the House of Representatives in Georgia.

During her time in the Georgia General Assembly, she introduced several bills that were sponsored by the League of Women Voters, an organization that encouraged women to use their new power to participate in shaping public policy.

She secured adoption of laws requiring better fire protection in orphanages, schools and children's hospitals.

A collection of her papers are held at the Middle Georgia Archives in the Washington Memorial Library in Macon.
