John Len Lacy, known as Len Lacy (September 8, 1900 – June 7, 1998),[1] was a Louisiana politician and businessman who served as a Democratic member of the Louisiana House of Representatives from Castor, Louisiana, from 1964 to 1968.[2]
Following Lacy's service, representation for his parish was combined with that of neighboring Jackson Parish, Louisiana, and Lacy was defeated in the 1967 Democratic primary by Jackson Parish native Edgerton L. "Bubba" Henry.[2] In 1970, The Shreveport Times named Lacy one of the most influential persons in Bienville Parish, for advice he gave on business and politics.
Lacy married Sallie Williams, with whom he had three daughters.[1]
