Pittsburgh’s history as an industrial hub began with coal mining, steel, and glass production. Until 1990, Pittsburgh engineers and Pittsburgh steel were part of every 40-story – or taller-skyscraper in the world. The city’s engineering role continues today as 1,600 technology companies – from huge corporations to hot new start-ups – maintain Pittsburgh offices, and 28% of Carnegie Mellon University students are enrolled in the School of Engineering, also known as the Carnegie Institute of Technology (you may have read about its respected robot reputation). Three rivers, the Allegheny, the Monongahala and the Ohio, converge in Pittsburgh, making necessary some civil engineering landmarks, including the Davis Island Lock and Dam and the Smithfield Street Bridge. Experience 1800s engineering with a view on the Duquesne Incline. The Carnegie Science Center offers inspiring STEM exhibits. The city’s David L. Lawrence Convention Center was the world’s first “green” convention center. And every sports fan knows, Pittsburgh’s home to Steelers, Penguins and Pirates. If you have time, 90-minutes away, you’ll find three Frank Lloyd Wright masterpieces: Fallingwater, Duncan House, and Kentuck Knob.
