A short history
The French built Fort Duquesne at the river junction in the 1750s, and the British took it and renamed the site after William Pitt. River trade and coal made Pittsburgh an industrial city, and by the late 1800s it was the steel capital of the US, home to Andrew Carnegie's mills. Carnegie's fortune funded the museums and libraries visitors still use. When steel collapsed in the 1980s, the city reinvented itself around education, medicine and technology.
