George Wellington "Cap" Streeter (c. 1837 – January 22, 1921) was an American who became infamous in Chicago for his real estate schemes and oftentimes bizarre eccentricity. From 1886 to 1921, Streeter, often through forgery and other manipulative means, attempted to lay claim to 186 acres (0.75 km2) of Lake Michigan shoreline from various owners.[1] Failing in his efforts to defraud wealthy landowners, he turned to selling the disputed land to uninformed buyers.[1][2] A portion of the real estate near downtown Chicago, known as Streeterville, is named for him.
