York Imperial Apple
York Township, York County, Pennsylvania
Marker Inscription
Here, at a nursery located on Springwood Farms, a new variety of apple was propagated by Jonathan Jessop in 1820. In 1855 it was named the "York Imperial." It became a leading variety which was widely grown in the U.S.

The Story
On the nursery grounds of Springwood Farms, orchardist Jonathan Jessop propagated a new apple in 1820 that kept firm and crisp through a long winter's storage. Decades later, in 1855, it took the name "York Imperial," and its keeping quality carried it into orchards across the country as one of America's leading commercial varieties. A single tree's chance seedling became a fixture of the nation's fruit trade.
Why it matters
The York Imperial is a reminder that American agricultural innovation happened tree by tree in local nurseries, shaping what the whole country grew and ate.
The story behind this marker
AI contextThe era
In the early 1800s, an apple was far more than a snack. It was winter food, cider, a way to store the calories of autumn deep into the cold months. On farms across the young republic, orchards were as practical as barns, and a variety that could survive months in a cellar without going soft was worth its weight in gold.
This was also the great age of American nurseries and amateur horticulture. Thousands of apple seedlings sprouted from discarded cores and deliberate plantings, and nearly every one was different. Most produced fruit fit only for cider or hogs. But every so often, a single tree bore something remarkable — and a sharp-eyed grower who noticed could change what an entire region planted.
The rolling farmland of York County was good orchard country, and it was here, on the grounds of a working nursery, that one such lucky discovery took root.
People & events
The marker credits Jonathan Jessop with propagating a new variety of apple in 1820, at a nursery on Springwood Farms. Propagating is the key word: an apple grown from seed rarely resembles its parent, so a promising tree must be deliberately multiplied by grafting to preserve it. Jessop recognized something worth keeping and made sure it survived beyond a single trunk.
What set this apple apart was its keeping quality — the ability to stay firm and edible long after harvest, through the lean end of winter. In an era before refrigeration, that was the trait growers prized above almost any other.
The variety carried its name in 1855, when it became the "York Imperial." From that point its reputation traveled, and it was widely grown across the United States as a leading commercial apple. One tree, noticed and nurtured on a Pennsylvania nursery, had become a fixture of the national fruit trade.
Its place in the American story
The story of the York Imperial is a small window onto how American agriculture actually advanced — not in laboratories at first, but tree by tree, in local orchards and nurseries, through the patient attention of growers who knew their plants. A named variety was a piece of living technology, shared by grafting and spread by reputation.
Apples like this shaped what the whole country ate. A hardy, long-keeping variety could feed families through winter, supply growing cities, and give commercial orchards a dependable crop to sell. Multiply that across the many regional apples of the 19th century, and you have the foundation of American fruit-growing.
There's a democratic quality to it, too. This wasn't a breakthrough handed down from on high; it began with one attentive person recognizing the value in a single tree. That is how much of the nation's agricultural abundance was built — locally, incrementally, and by people whose names we would otherwise never know.
If you visit
You won't find a dramatic monument here — this is landmark ground, a place to stand and think about beginnings. The reward is in the imagining: picture rows of young nursery trees on working farmland, and one among them quietly producing fruit good enough to change the region.
If you're touring in autumn, let this stop reframe how you see the orchards and farm stands of the surrounding countryside. The apples for sale down the road are the direct descendants of exactly this kind of patient horticulture, and a variety born here once traveled far beyond it.
It's a fine, low-key addition to a York County drive — the sort of marker that turns an ordinary landscape into a story. Read it, look out over the fields, and remember that a whole chapter of American farming can begin with a single well-tended tree.

America's First Iron Steamboat
Hellam Township, PA · est. 1947
In the 1820s, iron was an exotic material for shipbuilding, when nearly every hull afloat was made of wood. Yet in York, machinist John Elgar built the "Codorus," an iron-hulled steamboat, and launched it onto the Susquehanna on November 22, 1825. Named for a nearby creek, the little vessel is remembered as the first iron steamboat built in the United States.
Three Mile Island Historical Marker
Londonderry Township, PA
On March 28, 1979, a combination of equipment failures and human error at Three Mile Island's Unit 2 reactor triggered the worst commercial nuclear accident in U.S. history. Over several tense days radiation escaped, part of the reactor core melted down, and thousands of nearby residents fled their homes. The crisis gripped the nation and became a defining moment in the debate over atomic energy.
Early Telegraph
Mount Joy Township, PA · est. 1947
Along this railroad right-of-way ran the first commercial telegraph line in the United States, strung between Lancaster and Harrisburg and completed in 1845 — barely a year after Samuel Morse's famous demonstration. The first message clattered through in January 1846 with a very human impatience: "Why don't you write, you rascals?" It was a small joke carrying an enormous idea — that words could now outrun the fastest horse.
Daniel Drawbaugh
Lower Allen Township, PA · est. 1965
Daniel Drawbaugh, born in this village in 1827, was a self-taught mechanic who claimed to have devised a working telephone and sought a patent in 1880. Bell Telephone contested his claims, and in 1888 the courts decided in Bell's favor, leaving Drawbaugh a fascinating footnote in the contested history of the telephone. He worked on his inventions here until moving to nearby Camp Hill in 1904, where he died in 1911.
