steadily throughout the late 19th century, and the neighborhoods within the boundaries of modern Downtown diversified. To the northeast, around present-day Minute Maid Park, Quality Hill emerged as an elite neighborhood, occupied by entrepreneurs like William Marsh Rice (namesake of Rice University), William J. Hutchins, and William L. Foley (namesake of Foley's department stores). The neighborhood was well known for its opulent residential architecture, often in the Greek Revival style. To the north, along a bend in Buffalo Bayou, the working-class neighborhood of Frost Town welcomed immigrants from Europe and Mexico during the late 19th and early 20th centuries. Prior to the arrival of the first streetcars in Houston in the 1870s, most development in the city had been centered in and around the present-day Downtown area. One of the first systems, the Houston City Street Railway, opened in 1874 with four lines along the principal commercial thoroughfares in the heart of the business district. While generally focused on the most prosperous areas of town, the Houston City Street Railway extended one line a full mile south of the center of the city, making it the first streetcar network designed to spur residential development. By the 1890s, new, larger local streetcar companies finally accumulated the capital necessary to begin constructing streetcar suburbs beyond the conventional boundaries of the city. This led to the development and rapid growth of areas like the Houston Heights and Montrose. Residential development subsequently moved out of the central business district; Quality Hill was virtually abandoned by the turn of the 20th century. Downtown's growth can be attributed to two major factors: The first arose after the Galveston Hurricane of 1900, when investors began seeking a location close to the ports of Southwest Texas, but apparently free of the dangerous hurricanes that frequently struck Galveston and other port cities. Houston became a wise choice, as only the most powerful storms were able to reach the city. The second came a year later with the 1901 discovery of oil at Spindletop, just south of Beaumont, Texas. Shipping and oil industries began flocking to east Texas, many settling in Houston. From that point forward the area grew substantially, as many skyscrapers were constructed, including the city's tallest buildings. In the 1980s, however, economic recession canceled some projects and caused others to be scaled back, such as the Bank of the Southwest Tower. In the 19th century much of
