Insurance Company of North America
Philadelphia, Philadelphia County, Pennsylvania
Marker Inscription
Formed in 1792 at Independence Hall to write marine insurance and incorporated in 1794, it was the first US firm to insure a building's contents from fire. One of the most global insurers of the 20th century, INA created the homeowners policy in 1950. Located along "Insurance Row" (Walnut St. from 2nd to 6th) for much of the 19th century, and in the landmark INA Building at 1600 Arch St., 1925-91. Acquired by ACE (later Chubb) Ltd., 1999.

The Story
In 1792, at the very cradle of American governance, a group of Philadelphia merchants gathered at Independence Hall to found the Insurance Company of North America — the young republic's first stock insurance company, born to protect ships and cargo crossing dangerous seas. Chartered in 1794, INA soon broke new ground by insuring the contents of buildings against fire, and for generations clustered along the city's fabled "Insurance Row." By the 20th century it had grown into one of the world's great insurers, pioneering the modern homeowners policy in 1950 before being absorbed into what is now Chubb.
Why it matters
INA helped invent the American insurance industry, turning risk into a manageable commodity that underwrote commerce, home ownership, and the nation's economic expansion.
The story behind this marker
AI contextThe era
When a group of Philadelphia merchants set to work in 1792, the United States was barely a decade past declaring independence and only a few years into life under its new Constitution. Philadelphia was the young nation's largest city and, for a time, its capital — the beating heart of American commerce and government alike. Ships crowded the Delaware River wharves, carrying flour, timber, and manufactured goods out to the Atlantic world and returning with cargo from Europe and the Caribbean.
That trade was the lifeblood of the city, and it was dangerous. A single storm, a wreck on a shoal, or a wartime privateer could sink a merchant's entire fortune in an afternoon. Before organized American insurers existed, merchants often spread their risk informally or relied on underwriters across the ocean in London. The idea of pooling that risk at home, through a chartered American company, was very much of its moment — an experiment in self-reliance to match the political one.
It is fitting that the founders gathered at Independence Hall, the same rooms where the nation's founding documents had been debated. The building was a natural center of civic gravity, and starting a bold commercial venture in its shadow signaled ambition to match the era's optimism.
People & events
The company took shape in 1792 with a clear first purpose: marine insurance, protecting the ships and cargo that were Philadelphia's fortune. Two years later, in 1794, it received its formal incorporation — a legal milestone that gave it the standing and permanence of a chartered corporation rather than a loose partnership.
From there the firm's story is one of steady invention. It became the first American company to insure the contents of a building against fire — a genuinely new idea, extending protection from the hull of a ship to the goods and belongings inside four walls. For much of the nineteenth century it kept company with its peers along "Insurance Row," the stretch of Walnut Street between Second and Sixth where the city's underwriters clustered.
In the twentieth century the company grew into one of the most far-reaching insurers in the world, and in 1925 moved into its landmark building at 1600 Arch Street, its home for more than six decades. In 1950 it introduced the homeowners policy — bundling protections a family had once bought piecemeal into a single, familiar product. The long independent chapter closed in 1999, when the firm was acquired by ACE Ltd., which later took the name Chubb.
Its place in the American story
The rise of American insurance is one of the quieter engines of the nation's growth, and this company sits near its beginning. Insurance turns catastrophe into a calculable, shareable cost — and once risk can be managed, people are willing to take more of it. Merchants send ships, builders build, and families invest in homes they might otherwise be too cautious to buy.
The innovations tied to this firm trace that widening circle of protection: from cargo at sea, to the contents of a building, to the modern homeowners policy that millions of American families now take for granted. Each step brought insurance closer to ordinary life, and each helped underwrite the commerce and homeownership on which the American economy expanded.
That a company born in 1792 lived on — through mergers and new names — into the twenty-first century says something about how durable those foundations proved to be. The industry it helped pioneer became part of the invisible infrastructure of American prosperity.
If you visit
You're standing in one of the most storied corners of America. This is central Philadelphia, within the orbit of Independence Hall and the historic district, where the streets themselves carry the memory of the founding era. Take a moment to picture the merchants of the 1790s walking these blocks, worrying over ships still weeks out at sea.
If you wander toward Walnut Street between Second and Sixth, you're tracing the old "Insurance Row," where the city's underwriters once clustered shoulder to shoulder. The character of these blocks — brick, commerce, and centuries of foot traffic — still rewards a slow walk.
This marker pairs naturally with a day exploring Philadelphia's founding-era landmarks, but it adds a different thread to the usual story. Alongside the politics and the parchment, it reminds you that a new nation also had to invent the everyday machinery of business — including the unglamorous, essential idea of protecting people against loss.

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.
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.
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.
Anthony J. Drexel (1826-1893)
Philadelphia, PA · est. 2005
From an office on this site, financier Anthony J. Drexel built what the marker calls the world's first trans-Atlantic banking network, channeling European capital into the railroads and enterprises driving America's industrial boom. A noted philanthropist, he also founded the institution that became Drexel University. His firm helped make Philadelphia a hub of Gilded Age finance.
