Here in 1888 the young inventor Charles Martin Hall's method of producing aluminum by electrolysis was first put to commercial use by the Pittsburgh Reduction Company — the firm that would grow into industrial giant Alcoa. Before Hall's breakthrough, aluminum was a rare and costly novelty; his process made the lightweight metal cheap and abundant. What began as a Pittsburgh experiment turned aluminum into a staple of the modern age.

In 1869 a young inventor named George Westinghouse solved one of railroading's deadliest problems: how to stop a long train quickly and safely. His compressed-air brake let an engineer halt every car at once instead of relying on brakemen scrambling car to car. From this building his company grew into an industrial giant, and the technology he pioneered still slows trains around the world today.

Art Blakey grew up in Pittsburgh's vibrant Hill District, a cradle of jazz talent, and got his start with Billy Eckstine's pioneering band. A founder of the driving, blues-soaked style known as hard bop, Blakey led the Jazz Messengers for decades and turned the group into a legendary finishing school for young talent, launching the likes of Freddie Hubbard, Horace Silver, and Wynton Marsalis. His lifetime of achievement was crowned with a Grammy in 2005.

Founded in Pittsburgh in 1913 by brothers J.J. and Joseph Flannery, the Standard Chemical Company was the first commercial producer of radium in the United States — the earliest chapter of what would become the nuclear industry. Extracting the rare element from carnotite ore was painstaking, costly work at the frontier of science. In 1921 Marie Curie herself, radium's co-discoverer, visited the laboratory and was presented with a full gram of the element to support her research.
