Firsts in the World from Pittsburgh.
For two centuries Western Pennsylvania has been a cradle of invention in industry and technology in many fields, from medicine to manufacturing. The unique topography of hills and valleys required innovation in bridge-building and the transportation industry. The busy workshops and mills produced business entrepreneurs, engineers and inventors. Pittsburgh's growing population of laborers triggered firsts in hospital care, new educational programs, types of entertainment, and free public libraries. The heritage continues today in many forms, from educational programs such as Mister Roger's Neighborhood, to organ transplants, to bioengineering research and to designing the comunications network for computers.
