Sewickley Heights was established as a borough in 1935, but the area's character was largely established with the move of the Allegheny Country Club from Pittsburgh to its Sewickley Heights location in 1902. The establishment of the country club accelerated the settlement of the area as a haven for wealthy Pittsburgh residents. Many estates established in Sewickley Heights up through the 1930s occupied hundreds of acres with houses of immense proportions. Among the grandest estates was As You Like It, the estate of banker, shipper and investor William Thaw. As You Like It was featured in a 1903 print advertisement of the United States Battery Company that promoted electric lighting for country homes. Other notable estates included the Henry Robinson Rea mansion, Farmhill (which hosted Madame Curie in May 1921), and B. F. Jones' 100-room mansion, Fairacres.
