Surprise, Arizona is a young city founded by Flora Statler in 1938. She named the city because she would be "surprised if the town ever amounted to much." The town was believed to have been founded by her husband, a real estate developer named Homer Ludden, but property records in 2010 showed Statler was the owner before she met Ludden.
In the early years, Surprise was nothing more than a gas station and affordable homes for agricultural workers but it has grown rapidly since. Surprise was incorporated in 1960 and became a popular destination for retirees beginning in the 1990s and 2000s. This led to the development of Sun City Grand, an age-restricted community which has grown from 10,000 residents to 75,000 residents in 2004.
