Leaf was settled in 1838, and originally called "Salem". Most of the early settlers in the region were Irish, Scottish or English, and Salem's first families were the Thomsons, Cowarts, McKays, and McLeods.
Salem Academy was founded by W.W. Thompson, and operated between 1845 and 1862. Thompson later served as a Superintendent of Education of Greene County.
In 1902, three partners bought two sawmills in Leaf, as well as carts, oxen and wagons, and opened the Thomson Brothers Lumber Company. The mills had a total cutting capacity of 50,000 ft (15,000 m) per day, and produced longleaf yellow pine timber and lumber, dressed and rough. In 1903, the company sold the sawmills and nearly 1,600 acres (650 ha) of timber, to William F. Green of Bay Minette, Alabama. Green operated the mill under the named W.F. Green Lumber Company. The sawmill was destroyed by fire in 1906, at a loss of $20,000. The mill was rebuilt, but its operations ceased in 1909 when W.F. Green moved to Hattiesburg, Mississippi.
