Lehigh Acres was developed in the mid-1950s by Chicago businessman Lee Ratner. Seeking a tax shelter, Ratner had sold his pest control business and faced the possibility of losing most of his earnings to the high capital gains tax of that era. Ratner heard that cattle was a good investment for people in his predicament, and he bought 18,000 acres (73 km2) of land in eastern Lee County and named it the Lucky Lee Ranch.
