The Lemos family originated in Chios and had been involved in shipping since the eighteenth century. Christos M. Lemos became part-owner of a steamer in 1905. His sons George, Michael and Leon joined Pateras relatives to form Lemos & Pateras in London in 1937. The brothers bought the Liberty ship Hellas and established an American office in 1947; G. Lemos Brothers followed in London in 1948. Captain Leon formed Efploia in 1967, with his son-in-law Spyros Patitsas entering the business in 1968. A later family account adds that fifteen of seventeen ships were sold in 1980 before the market crash and Leon returned in 1985.
