Frank Lyon was a prominent Arlington politician and developer. During the late 1910s and early 1920s Frank Lyon and his Lyon & Fitch Realty Company subdivided and sold 465 acres in Arlington – nearly three percent of all the land in the county. These acres were divided between his two communities: Lyon Park and Lyon Village. The Lyon properties helped to transform Arlington’s built environment through their focus on pre-planned suburban subdivisions. Lyon also shaped county affairs as a member of the Good Citizen's League social and political organization, and as owner of "The Monitor" newspaper.
