Pittsburgh, Pennsylvania provides
a wonderful example of a city that saw great prosperity at the start
of the twentieth century but fell victim to the economic slowdown that
took place just decades later. Many Brownfields exist throughout Pittsburgh
and a few have already been redeveloped and now serve as prime examples
of the possibilities that exist for these long neglected structures.
Pittsburgh flourished in the late 19th century
as a city with a proud economy based in the coal and steel industries.
Perhaps the greatest benefactor of Pittsburgh was Andrew Carnegie. During
his lifetime Carnegie donated over $350 million to city organizations
and helped create many institutions himself. In 1900 he gave $1 million
for the creation of the Carnegie Technical Schools (the school later
became known as Carnegie Mellon University.) The creation of this school
allowed for new advancements in technological fields and provided a
labor pool to nearby industry.
The availability of raw material and skilled
labor, a fortunate location at the intersection of the Allegheny, Ohio,
and Monongahela Rivers (allowing for efficient transportation of materials),
along with a dozen resident millionaires lead to Pittsburgh's rise as
one of the most productive American cities at the turn of the century.
By 1893 the J&L Corporation dominated Pittsburgh's
steel industry, controlling most of the city's south side the owner
soon expanded the business to include iron, a decision that proved quite
profitable. This corporation developed many factories and other industrial
complexes throughout the south side of Pittsburgh. J&L owned the
steel, iron, lumber, and rolling mills which employed many Pittsburgh
residents over the company's 40 year presence in the city.
The steel and iron industries continued to thrive
throughout the beginning of the 20th century, supported largely by the
federal government's involvement in World Wars I and II. Though a few
industrial complexes were closed there was little concern about their
impact on the urban landscape. As long as businesses were successful
and citizens were employed there was no need for the city government
to concern themselves with these abandoned sites. However, as technology
advanced the need for steel and iron drastically decreased, leaving
Pittsburgh a desolate skeleton of its former self.
