The Story

In the spring of 1840, only months after photography was announced to an astonished world, the Philadelphia metallurgist and brass founder Robert Cornelius opened one of its very first commercial studios here. Working with chemist Paul Beck Goddard, he found ways to shorten exposure times dramatically — the breakthrough that made it possible to sit for a portrait without holding still for agonizing minutes. Cornelius had already made himself one of the first people ever photographed.

Why it matters

His work helped turn the camera from a curiosity into an everyday tool of American life, democratizing the portrait once reserved for those who could afford a painter.

Siegmund Lubin (1851-1923)

Philadelphia, PA · est. 1994

From an optical shop on this block in 1897, Siegmund Lubin built one of America's first great motion-picture empires — six studios across five states — earning fame as the first movie mogul. A tinkerer and shrewd marketer, he helped turn flickering novelties into a popular entertainment that drew ordinary Americans into darkened theaters. The industry he helped create outgrew him; bankrupt by 1916, he died in obscurity.

John Nepomuk Maelzel (1772-1838)

Philadelphia, PA · est. 2004

In the 1820s Johann Nepomuk Maelzel brought his traveling wonders to a Philadelphia exhibition hall, chief among them the Automaton Chess Player known as "The Turk," a mechanical marvel that appeared to play chess against all comers. A German-born inventor and showman, Maelzel is also credited with popularizing the metronome and crafting ear trumpets for the deaf Beethoven. His hall drew crowds eager to puzzle over the boundary between machine and illusion.

PSFS Building

Philadelphia, PA · est. 2005

Completed in 1932 at the depths of the Great Depression, the Philadelphia Saving Fund Society Building rose as America's first International Style skyscraper—a sleek tower of glass, steel, and stone that rejected the ornate columns and cornices then expected of a bank. Designed to broadcast modernity and stability, it embraced cutting-edge structural engineering, high-speed elevators, and air conditioning, announcing that the future of American architecture had arrived on Market Street.

The Philadelphia Contributionship

Philadelphia, PA · est. 1954

Founded in 1752 by Benjamin Franklin and a group of his fellow citizens, the Philadelphia Contributionship was the oldest fire insurance company in America, pooling members' risk to protect their houses against loss by fire. Born of Franklin's practical genius for civic improvement, it turned mutual cooperation into a lasting institution in a city all too familiar with the threat of flames.
