He founded Harmony Grove Mills and established the Hardman Sanitorium, demonstrating entrepreneurial acumen. Hardman became a prominent figure in north Georgia, owning extensive orchards and pioneering agricultural innovations. He served in various political roles, including terms in the Georgia General Assembly and as Governor, where he focused on improving governmental efficiency and infrastructure.

Lamartine Hardman's political identity is marked by a unique blend of progressive public health initiatives and conservative economic measures. His introduction of agricultural courses in public schools and establishment of the State Board of Health show a progressive stance on education and public health, yet his prohibition policies and allowance of executions despite confessions reveal a rigidly conservative approach to social issues. Hardman's tenure as Federal Fuel Administrator during World War I demonstrates an ideologically agile approach to economic policy, balancing wartime necessities with regional economic impacts.
