The Story

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.

Why it matters

Maelzel embodies the early-19th-century American appetite for scientific spectacle, standing at the crossroads of genuine invention and theatrical humbug that would later shape figures like P.T. Barnum.

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.

Benjamin Franklin (1706-1790)

Philadelphia, PA · est. 1990

Benjamin Franklin, arguably the eighteenth century's most versatile American, built a fine brick house in this Philadelphia courtyard beginning in 1763. After decades abroad as a printer, diplomat, and revolutionary statesman, he returned to live his final five years here until his death in 1790. From this address the aging Franklin remained a fixture of the young nation's public life, corresponding, inventing, and advising to the last.

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.

Robert Cornelius

Philadelphia, PA · est. 1994

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.
